//
// isDebug: Boolean
// Defaults to `false`. If set to `true`, ensures that Dojo provides
// extended debugging feedback via Firebug. If Firebug is not available
// on your platform, setting `isDebug` to `true` will force Dojo to
// pull in (and display) the version of Firebug Lite which is
// integrated into the Dojo distribution, thereby always providing a
// debugging/logging console when `isDebug` is enabled. Note that
// Firebug's `console.*` methods are ALWAYS defined by Dojo. If
// `isDebug` is false and you are on a platform without Firebug, these
// methods will be defined as no-ops.
isDebug: false,
// debugAtAllCosts: Boolean
// Defaults to `false`. If set to `true`, this triggers an alternate
// mode of the package system in which dependencies are detected and
// only then are resources evaluated in dependency order via
// `<script>` tag inclusion. This may double-request resources and
// cause problems with scripts which expect `dojo.require()` to
// preform synchronously. `debugAtAllCosts` can be an invaluable
// debugging aid, but when using it, ensure that all code which
// depends on Dojo modules is wrapped in `dojo.addOnLoad()` handlers.
// Due to the somewhat unpredictable side-effects of using
// `debugAtAllCosts`, it is strongly recommended that you enable this
// flag as a last resort. `debugAtAllCosts` has no effect when loading
// resources across domains. For usage information, see the

// calls to `dojo.requireLocalization()` are processed.
extraLocale: undefined,
// baseUrl: String
// The directory in which `dojo.js` is located. Under normal
// conditions, Dojo auto-detects the correct location from which it
// was loaded. You may need to manually configure `baseUrl` in cases
// where you have renamed `dojo.js` or in which `<base>` tags confuse
// some browsers (e.g. IE 6). The variable `dojo.baseUrl` is assigned
// either the value of `djConfig.baseUrl` if one is provided or the
// auto-detected root if not. Other modules are located relative to
// this path. The path should end in a slash.
baseUrl: undefined,
// modulePaths: Object
// A map of module names to paths relative to `dojo.baseUrl`. The
// key/value pairs correspond directly to the arguments which
// `dojo.registerModulePath` accepts. Specifiying

afterOnLoad: false,

ioPublish: false,
// useCustomLogger: Anything?
// If set to a value that evaluates to true such as a string or array and
// isDebug is true and Firebug is not available or running, then it bypasses
// the creation of Firebug Lite allowing you to define your own console object.

// For IE only, skip the DOMContentLoaded hack used. Sometimes it can cause an Operation
// Aborted error if the rest of the page triggers script defers before the DOM is ready.
// If this is config value is set to true, then dojo.addOnLoad callbacks will not be
// triggered until the page load event, which is after images and iframes load. If you

// when called as `dojo.require("a.b.c", true)`
// description:
// Modules are loaded via dojo.require by using one of two loaders: the normal loader
// and the xdomain loader. The xdomain loader is used when dojo was built with a
// custom build that specified loader=xdomain and the module lives on a modulePath
// that is a whole URL, with protocol and a domain. The versions of Dojo that are on
// the Google and AOL CDNs use the xdomain loader.
//
// If the module is loaded via the xdomain loader, it is an asynchronous load, since
// the module is added via a dynamically created script tag. This
// means that dojo.require() can return before the module has loaded. However, this
// should only happen in the case where you do dojo.require calls in the top-level
// HTML page, or if you purposely avoid the loader checking for dojo.require
// dependencies in your module by using a syntax like dojo["require"] to load the module.
//
// Sometimes it is useful to not have the loader detect the dojo.require calls in the
// module so that you can dynamically load the modules as a result of an action on the
// page, instead of right at module load time.
//
// Also, for script blocks in an HTML page, the loader does not pre-process them, so
// it does not know to download the modules before the dojo.require calls occur.
//
// So, in those two cases, when you want on-the-fly module loading or for script blocks
// in the HTML page, special care must be taken if the dojo.required code is loaded
// asynchronously. To make sure you can execute code that depends on the dojo.required
// modules, be sure to add the code that depends on the modules in a dojo.addOnLoad()
// callback. dojo.addOnLoad waits for all outstanding modules to finish loading before
// executing. Example:
//
// | <script type="text/javascript">
// | dojo.require("foo");
// | dojo.require("bar");
// | dojo.addOnLoad(function(){
// | //you can now safely do something with foo and bar
// | });
// | </script>
//
// This type of syntax works with both xdomain and normal loaders, so it is good
// practice to always use this idiom for on-the-fly code loading and in HTML script
// blocks. If at some point you change loaders and where the code is loaded from,
// it will all still work.
//
// More on how dojo.require
// `dojo.require("A.B")` first checks to see if symbol A.B is
// defined. If it is, it is simply returned (nothing to do).
//
// If it is not defined, it will look for `A/B.js` in the script root
// directory.
//
// `dojo.require` throws an excpetion if it cannot find a file
// to load, or if the symbol `A.B` is not defined after loading.
//
// It returns the object `A.B`, but note the caveats above about on-the-fly loading and
// HTML script blocks when the xdomain loader is loading a module.
//
// `dojo.require()` does nothing about importing symbols into
// the current namespace. It is presumed that the caller will
// take care of that. For example, to import all symbols into a
// local block, you might write:
//
// | with (dojo.require("A.B")) {
// | ...
// | }
//
// And to import just the leaf symbol to a local variable:
//
// | var B = dojo.require("A.B");
// | ...
// returns: the required namespace object

// `dojo.provide("dojo.foo");` before any calls to
// `dojo.require()` are made.
//
// For backwards compatibility reasons, in addition to registering
// the resource, `dojo.provide()` also ensures that the javascript
// object for the module exists. For example,
// `dojo.provide("dojox.data.FlickrStore")`, in addition to
// registering that `FlickrStore.js` is a resource for the
// `dojox.data` module, will ensure that the `dojox.data`
// javascript object exists, so that calls like
// `dojo.data.foo = function(){ ... }` don't fail.

// Note that the two bundles in the example do not define all the
// same variants. For a given locale, bundles will be loaded for
// that locale and all more general locales above it, including a
// fallback at the root directory. For example, a declaration for
// the "de-at" locale will first load `nls/de-at/bundleone.js`,

// will follow this cascading pattern. An optional build step can
// preload the bundles to avoid data redundancy and the multiple
// network hits normally required to load these resources.
//

//
// bundleName:
// bundle name, i.e. the filename without the '.js' suffix. Using "nls" as a

// description:
// Create a constructor using a compact notation for inheritance and
// prototype extension.
//
// Mixin ancestors provide a type of multiple inheritance.
// Prototypes of mixin ancestors are copied to the new class:
// changes to mixin prototypes will not affect classes to which
// they have been mixed in.
//
// Ancestors can be compound classes created by this version of
// dojo.declare. In complex cases all base classes are going to be
// linearized according to C3 MRO algorithm
// (see http://www.python.org/download/releases/2.3/mro/ for more
// details).
//
// "className" is cached in "declaredClass" property of the new class,
// if it was supplied. The immediate super class will be cached in
// "superclass" property of the new class.
//
// Methods in "props" will be copied and modified: "nom" property
// (the declared name of the method) will be added to all copied
// functions to help identify them for the internal machinery. Be
// very careful, while reusing methods: if you use the same
// function under different names, it can produce errors in some
// cases.
//
// It is possible to use constructors created "manually" (without
// dojo.declare) as bases. They will be called as usual during the
// creation of an instance, their methods will be chained, and even
// called by "this.inherited()".
//
// Special property "-chains-" governs how to chain methods. It is
// a dictionary, which uses method names as keys, and hint strings
// as values. If a hint string is "after", this method will be
// called after methods of its base classes. If a hint string is
// "before", this method will be called before methods of its base
// classes.
//
// If "constructor" is not mentioned in "-chains-" property, it will
// be chained using the legacy mode: using "after" chaining,
// calling preamble() method before each constructor, if available,
// and calling postscript() after all constructors were executed.
// If the hint is "after", it is chained as a regular method, but
// postscript() will be called after the chain of constructors.
// "constructor" cannot be chained "before", but it allows
// a special hint string: "manual", which means that constructors
// are not going to be chained in any way, and programmer will call
// them manually using this.inherited(). In the latter case
// postscript() will be called after the construction.
//
// All chaining hints are "inherited" from base classes and
// potentially can be overridden. Be very careful when overriding
// hints! Make sure that all chained methods can work in a proposed
// manner of chaining.
//
// Once a method was chained, it is impossible to unchain it. The
// only exception is "constructor". You don't need to define a
// method in order to supply a chaining hint.
//
// If a method is chained, it cannot use this.inherited() because
// all other methods in the hierarchy will be called automatically.
//
// Usually constructors and initializers of any kind are chained
// using "after" and destructors of any kind are chained as
// "before". Note that chaining assumes that chained methods do not
// return any value: any returned value will be discarded.
//
// example:
// | dojo.declare("my.classes.bar", my.classes.foo, {
// | // properties to be added to the class prototype
// | someValue: 2,
// | // initialization function
// | constructor: function(){
// | this.myComplicatedObject = new ReallyComplicatedObject();
// | },
// | // other functions
// | someMethod: function(){
// | doStuff();
// | }
// | });
//
// example:
// | var MyBase = dojo.declare(null, {
// | // constructor, properties, and methods go here
// | // ...
// | });
// | var MyClass1 = dojo.declare(MyBase, {
// | // constructor, properties, and methods go here

// | });
// | var MyClass2 = dojo.declare(MyBase, {

// | // ...
// | });
// | var MyDiamond = dojo.declare([MyClass1, MyClass2], {
// | // constructor, properties, and methods go here
// | // ...
// | });
//
// example:
// | var F = function(){ console.log("raw constructor"); };
// | F.prototype.method = function(){
// | console.log("raw method");
// | };
// | var A = dojo.declare(F, {

// | new A().method();
// | // will print:

// | // A.constructor

// `dojo.connect` is the core event handling and delegation method in

// be either regular function calls or DOM events.
//
// description:
// Connects listeners to actions, so that after event fires, a
// listener is called with the same arguments passed to the orginal
// function.
//
// Since `dojo.connect` allows the source of events to be either a
// "regular" JavaScript function or a DOM event, it provides a uniform
// interface for listening to all the types of events that an
// application is likely to deal with though a single, unified
// interface. DOM programmers may want to think of it as
// "addEventListener for everything and anything".
//
// When setting up a connection, the `event` parameter must be a
// string that is the name of the method/event to be listened for. If
// `obj` is null, `dojo.global` is assumed, meaning that connections
// to global methods are supported but also that you may inadvertantly
// connect to a global by passing an incorrect object name or invalid
// reference.
//
// `dojo.connect` generally is forgiving. If you pass the name of a
// function or method that does not yet exist on `obj`, connect will
// not fail, but will instead set up a stub method. Similarly, null
// arguments may simply be omitted such that fewer than 4 arguments
// may be required to set up a connection See the examples for deails.
//
// The return value is a handle that is needed to
// remove this connection with `dojo.disconnect`.
//
// obj:
// The source object for the event function.
// Defaults to `dojo.global` if null.
// If obj is a DOM node, the connection is delegated
// to the DOM event manager (unless dontFix is true).
//
// event:
// String name of the event function in obj.
// I.e. identifies a property `obj[event]`.
//
// context:
// The object that method will receive as "this".
//
// If context is null and method is a function, then method
// inherits the context of event.
//
// If method is a string then context must be the source
// object object for method (context[method]). If context is null,
// dojo.global is used.
//
// method:
// A function reference, or name of a function in context.
// The function identified by method fires after event does.
// method receives the same arguments as the event.
// See context argument comments for information on method's scope.
//
// dontFix:
// If obj is a DOM node, set dontFix to true to prevent delegation
// of this connection to the DOM event manager.

// summary:
// Encapsulates a sequence of callbacks in response to a value that
// may not yet be available. This is modeled after the Deferred class
// from Twisted <http://twistedmatrix.com>.
// description:
// JavaScript has no threads, and even if it did, threads are hard.
// Deferreds are a way of abstracting non-blocking events, such as the
// final response to an XMLHttpRequest. Deferreds create a promise to
// return a response a some point in the future and an easy way to
// register your interest in receiving that response.
//
// The most important methods for Deffered users are:
//
// * addCallback(handler)
// * addErrback(handler)
// * callback(result)
// * errback(result)
//
// In general, when a function returns a Deferred, users then "fill
// in" the second half of the contract by registering callbacks and
// error handlers. You may register as many callback and errback
// handlers as you like and they will be executed in the order
// registered when a result is provided. Usually this result is
// provided as the result of an asynchronous operation. The code
// "managing" the Deferred (the code that made the promise to provide
// an answer later) will use the callback() and errback() methods to
// communicate with registered listeners about the result of the
// operation. At this time, all registered result handlers are called
// *with the most recent result value*.
//
// Deferred callback handlers are treated as a chain, and each item in
// the chain is required to return a value that will be fed into
// successive handlers. The most minimal callback may be registered
// like this:
//
// | var d = new dojo.Deferred();
// | d.addCallback(function(result){ return result; });
//
// Perhaps the most common mistake when first using Deferreds is to
// forget to return a value (in most cases, the value you were
// passed).
//
// The sequence of callbacks is internally represented as a list of
// 2-tuples containing the callback/errback pair. For example, the
// following call sequence:
//
// | var d = new dojo.Deferred();
// | d.addCallback(myCallback);
// | d.addErrback(myErrback);
// | d.addBoth(myBoth);
// | d.addCallbacks(myCallback, myErrback);
//
// is translated into a Deferred with the following internal
// representation:
//
// | [
// | [myCallback, null],
// | [null, myErrback],
// | [myBoth, myBoth],
// | [myCallback, myErrback]
// | ]
//
// The Deferred also keeps track of its current status (fired). Its
// status may be one of three things:
//
// * -1: no value yet (initial condition)
// * 0: success
// * 1: error
//
// A Deferred will be in the error state if one of the following three
// conditions are met:
//
// 1. The result given to callback or errback is "instanceof" Error
// 2. The previous callback or errback raised an exception while
// executing
// 3. The previous callback or errback returned a value
// "instanceof" Error
//
// Otherwise, the Deferred will be in the success state. The state of
// the Deferred determines the next element in the callback sequence
// to run.
//
// When a callback or errback occurs with the example deferred chain,
// something equivalent to the following will happen (imagine
// that exceptions are caught and returned):
//
// | // d.callback(result) or d.errback(result)
// | if(!(result instanceof Error)){
// | result = myCallback(result);
// | }
// | if(result instanceof Error){
// | result = myErrback(result);
// | }
// | result = myBoth(result);
// | if(result instanceof Error){
// | result = myErrback(result);
// | }else{
// | result = myCallback(result);
// | }
//
// The result is then stored away in case another step is added to the
// callback sequence. Since the Deferred already has a value
// available, any new callbacks added will be called immediately.
//
// There are two other "advanced" details about this implementation
// that are useful:
//
// Callbacks are allowed to return Deferred instances themselves, so
// you can build complicated sequences of events with ease.
//
// The creator of the Deferred may specify a canceller. The canceller
// is a function that will be called if Deferred.cancel is called
// before the Deferred fires. You can use this to implement clean
// aborting of an XMLHttpRequest, etc. Note that cancel will fire the
// deferred with a CancelledError (unless your canceller returns
// another kind of error), so the errbacks should be prepared to
// handle that error for cancellable Deferreds.
// example:
// | var deferred = new dojo.Deferred();
// | setTimeout(function(){ deferred.callback({success: true}); }, 1000);
// | return deferred;
// example:
// Deferred objects are often used when making code asynchronous. It
// may be easiest to write functions in a synchronous manner and then
// split code using a deferred to trigger a response to a long-lived
// operation. For example, instead of register a callback function to
// denote when a rendering operation completes, the function can
// simply return a deferred:
//
// | // callback style:
// | function renderLotsOfData(data, callback){
// | var success = false
// | try{
// | for(var x in data){
// | renderDataitem(data[x]);
// | }
// | success = true;
// | }catch(e){ }
// | if(callback){
// | callback(success);
// | }
// | }
//
// | // using callback style
// | renderLotsOfData(someDataObj, function(success){
// | // handles success or failure
// | if(!success){
// | promptUserToRecover();
// | }
// | });
// | // NOTE: no way to add another callback here!!
// example:
// Using a Deferred doesn't simplify the sending code any, but it
// provides a standard interface for callers and senders alike,
// providing both with a simple way to service multiple callbacks for
// an operation and freeing both sides from worrying about details
// such as "did this get called already?". With Deferreds, new
// callbacks can be added at any time.
//
// | // Deferred style:
// | function renderLotsOfData(data){
// | var d = new dojo.Deferred();
// | try{
// | for(var x in data){
// | renderDataitem(data[x]);
// | }
// | d.callback(true);
// | }catch(e){
// | d.errback(new Error("rendering failed"));
// | }
// | return d;
// | }
//
// | // using Deferred style
// | renderLotsOfData(someDataObj).addErrback(function(){
// | promptUserToRecover();
// | });
// | // NOTE: addErrback and addCallback both return the Deferred
// | // again, so we could chain adding callbacks or save the
// | // deferred for later should we need to be notified again.
// example:
// In this example, renderLotsOfData is syncrhonous and so both
// versions are pretty artificial. Putting the data display on a
// timeout helps show why Deferreds rock:
//
// | // Deferred style and async func
// | function renderLotsOfData(data){
// | var d = new dojo.Deferred();
// | setTimeout(function(){
// | try{
// | for(var x in data){
// | renderDataitem(data[x]);
// | }
// | d.callback(true);
// | }catch(e){
// | d.errback(new Error("rendering failed"));
// | }
// | }, 100);
// | return d;
// | }
//

// Otherwise, in some cases, some browsers will not apply the style.

// summary:
// dojo.NodeList is an of Array subclass which adds syntactic
// sugar for chaining, common iteration operations, animation, and
// node manipulation. NodeLists are most often returned as the
// result of dojo.query() calls.
// description:
// dojo.NodeList instances provide many utilities that reflect
// core Dojo APIs for Array iteration and manipulation, DOM
// manipulation, and event handling. Instead of needing to dig up
// functions in the dojo.* namespace, NodeLists generally make the
// full power of Dojo available for DOM manipulation tasks in a
// simple, chainable way.
// example:
// create a node list from a node
// | new dojo.NodeList(dojo.byId("foo"));
// example:
// get a NodeList from a CSS query and iterate on it
// | var l = dojo.query(".thinger");
// | l.forEach(function(node, index, nodeList){
// | console.log(index, node.innerHTML);
// | });
// example:
// use native and Dojo-provided array methods to manipulate a
// NodeList without needing to use dojo.* functions explicitly:
// | var l = dojo.query(".thinger");
// | // since NodeLists are real arrays, they have a length
// | // property that is both readable and writable and
// | // push/pop/shift/unshift methods
// | console.log(l.length);
// | l.push(dojo.create("span"));
// |
// | // dojo's normalized array methods work too:
// | console.log( l.indexOf(dojo.byId("foo")) );
// | // ...including the special "function as string" shorthand
// | console.log( l.every("item.nodeType == 1") );
// |
// | // NodeLists can be [..] indexed, or you can use the at()
// | // function to get specific items wrapped in a new NodeList:
// | var node = l[3]; // the 4th element
// | var newList = l.at(1, 3); // the 2nd and 4th elements
// example:
// the style functions you expect are all there too:
// | // style() as a getter...
// | var borders = dojo.query(".thinger").style("border");
// | // ...and as a setter:
// | dojo.query(".thinger").style("border", "1px solid black");
// | // class manipulation
// | dojo.query("li:nth-child(even)").addClass("even");
// | // even getting the coordinates of all the items
// | var coords = dojo.query(".thinger").coords();
// example:
// DOM manipulation functions from the dojo.* namespace area also
// available:
// | // remove all of the elements in the list from their
// | // parents (akin to "deleting" them from the document)
// | dojo.query(".thinger").orphan();
// | // place all elements in the list at the front of #foo
// | dojo.query(".thinger").place("foo", "first");
// example:
// Event handling couldn't be easier. `dojo.connect` is mapped in,
// and shortcut handlers are provided for most DOM events:
// | // like dojo.connect(), but with implicit scope
// | dojo.query("li").connect("onclick", console, "log");
// |
// | // many common event handlers are already available directly:
// | dojo.query("li").onclick(console, "log");
// | var toggleHovered = dojo.hitch(dojo, "toggleClass", "hovered");
// | dojo.query("p")
// | .onmouseenter(toggleHovered)
// | .onmouseleave(toggleHovered);
// example:
// chainability is a key advantage of NodeLists:
// | dojo.query(".thinger")
// | .onclick(function(e){ /* ... */ })
// | .at(1, 3, 8) // get a subset
// | .style("padding", "5px")
// | .forEach(console.log);

/*
dojo.query() architectural overview:
dojo.query is a relatively full-featured CSS3 query library. It is
designed to take any valid CSS3 selector and return the nodes matching
the selector. To do this quickly, it processes queries in several
steps, applying caching where profitable.
The steps (roughly in reverse order of the way they appear in the code):
1.) check to see if we already have a "query dispatcher"
- if so, use that with the given parameterization. Skip to step 4.
2.) attempt to determine which branch to dispatch the query to:
- JS (optimized DOM iteration)
- native (FF3.1+, Safari 3.1+, IE 8+)
3.) tokenize and convert to executable "query dispatcher"
- this is where the lion's share of the complexity in the
system lies. In the DOM version, the query dispatcher is
assembled as a chain of "yes/no" test functions pertaining to
a section of a simple query statement (".blah:nth-child(odd)"
but not "div div", which is 2 simple statements). Individual
statement dispatchers are cached (to prevent re-definition)
as are entire dispatch chains (to make re-execution of the
same query fast)
4.) the resulting query dispatcher is called in the passed scope
(by default the top-level document)
- for DOM queries, this results in a recursive, top-down
evaluation of nodes based on each simple query section
- for native implementations, this may mean working around spec
bugs. So be it.
5.) matched nodes are pruned to ensure they are unique (if necessary)

// summary:
// Returns nodes which match the given CSS3 selector, searching the

// description:
// dojo.query() is the swiss army knife of DOM node manipulation in
// Dojo. Much like Prototype's "$$" (bling-bling) function or JQuery's
// "$" function, dojo.query provides robust, high-performance
// CSS-based node selector support with the option of scoping searches
// to a particular sub-tree of a document.
//
// Supported Selectors:
// --------------------
//
// dojo.query() supports a rich set of CSS3 selectors, including:
//
// * class selectors (e.g., `.foo`)
// * node type selectors like `span`
// * ` ` descendant selectors
// * `>` child element selectors
// * `#foo` style ID selectors
// * `*` universal selector
// * `~`, the immediately preceeded-by sibling selector
// * `+`, the preceeded-by sibling selector
// * attribute queries:
// | * `[foo]` attribute presence selector
// | * `[foo='bar']` attribute value exact match
// | * `[foo~='bar']` attribute value list item match
// | * `[foo^='bar']` attribute start match
// | * `[foo$='bar']` attribute end match
// | * `[foo*='bar']` attribute substring match
// * `:first-child`, `:last-child`, and `:only-child` positional selectors
// * `:empty` content emtpy selector
// * `:checked` pseudo selector
// * `:nth-child(n)`, `:nth-child(2n+1)` style positional calculations
// * `:nth-child(even)`, `:nth-child(odd)` positional selectors
// * `:not(...)` negation pseudo selectors
//
// Any legal combination of these selectors will work with
// `dojo.query()`, including compound selectors ("," delimited).
// Very complex and useful searches can be constructed with this
// palette of selectors and when combined with functions for
// manipulation presented by dojo.NodeList, many types of DOM
// manipulation operations become very straightforward.
//
// Unsupported Selectors:
// ----------------------
//
// While dojo.query handles many CSS3 selectors, some fall outside of
// what's resaonable for a programmatic node querying engine to
// handle. Currently unsupported selectors include:
//
// * namespace-differentiated selectors of any form
// * all `::` pseduo-element selectors
// * certain pseduo-selectors which don't get a lot of day-to-day use:
// | * `:root`, `:lang()`, `:target`, `:focus`
// * all visual and state selectors:
// | * `:root`, `:active`, `:hover`, `:visisted`, `:link`,
// `:enabled`, `:disabled`
// * `:*-of-type` pseudo selectors
//
// dojo.query and XML Documents:
// -----------------------------
//
// `dojo.query` (as of dojo 1.2) supports searching XML documents
// in a case-sensitive manner. If an HTML document is served with
// a doctype that forces case-sensitivity (e.g., XHTML 1.1
// Strict), dojo.query() will detect this and "do the right
// thing". Case sensitivity is dependent upon the document being
// searched and not the query used. It is therefore possible to
// use case-sensitive queries on strict sub-documents (iframes,
// etc.) or XML documents while still assuming case-insensitivity
// for a host/root document.
//
// Non-selector Queries:
// ---------------------
//
// If something other than a String is passed for the query,
// `dojo.query` will return a new `dojo.NodeList` instance
// constructed from that parameter alone and all further
// processing will stop. This means that if you have a reference
// to a node or NodeList, you can quickly construct a new NodeList
// from the original by calling `dojo.query(node)` or
// `dojo.query(list)`.
//
// query:
// The CSS3 expression to match against. For details on the syntax of
// CSS3 selectors, see <http://www.w3.org/TR/css3-selectors/#selectors>
// root:
// A DOMNode (or node id) to scope the search from. Optional.
// returns: dojo.NodeList
// An instance of `dojo.NodeList`. Many methods are available on
// NodeLists for searching, iterating, manipulating, and handling
// events on the matched nodes in the returned list.
// example:
// search the entire document for elements with the class "foo":
// | dojo.query(".foo");
// these elements will match:
// | <span class="foo"></span>
// | <span class="foo bar"></span>
// | <p class="thud foo"></p>
// example:
// search the entire document for elements with the classes "foo" *and* "bar":
// | dojo.query(".foo.bar");
// these elements will match:
// | <span class="foo bar"></span>
// while these will not:
// | <span class="foo"></span>
// | <p class="thud foo"></p>
// example:
// find `<span>` elements which are descendants of paragraphs and
// which have a "highlighted" class:
// | dojo.query("p span.highlighted");
// the innermost span in this fragment matches:
// | <p class="foo">
// | <span>...
// | <span class="highlighted foo bar">...</span>
// | </span>
// | </p>
// example:
// set an "odd" class on all odd table rows inside of the table
// `#tabular_data`, using the `>` (direct child) selector to avoid
// affecting any nested tables:
// | dojo.query("#tabular_data > tbody > tr:nth-child(odd)").addClass("odd");
// example:
// remove all elements with the class "error" from the document
// and store them in a list:
// | var errors = dojo.query(".error").orphan();
// example:
// add an onclick handler to every submit button in the document
// which causes the form to be sent via Ajax instead:
// | dojo.query("input[type='submit']").onclick(function(e){
// | dojo.stopEvent(e); // prevent sending the form
// | var btn = e.target;
// | dojo.xhrPost({
// | form: btn.form,
// | load: function(data){
// | // replace the form with the response
// | var div = dojo.doc.createElement("div");
// | dojo.place(div, btn.form, "after");

// description:
// `dojo.animateProperty` is the foundation of most `dojo.fx`
// animations. It takes an object of "properties" corresponding to
// style properties, and animates them in parallel over a set
// duration.
//
// example:
// A simple animation that changes the width of the specified node.
// | dojo.animateProperty({
// | node: "nodeId",
// | properties: { width: 400 },
// | }).play();
// Dojo figures out the start value for the width and converts the
// integer specified for the width to the more expressive but
// verbose form `{ width: { end: '400', units: 'px' } }` which you
// can also specify directly. Defaults to 'px' if ommitted.
//
// example:
// Animate width, height, and padding over 2 seconds... the
// pedantic way:
// | dojo.animateProperty({ node: node, duration:2000,
// | properties: {
// | width: { start: '200', end: '400', units:"px" },
// | height: { start:'200', end: '400', units:"px" },
// | paddingTop: { start:'5', end:'50', units:"px" }
// | }
// | }).play();
// Note 'paddingTop' is used over 'padding-top'. Multi-name CSS properties
// are written using "mixed case", as the hyphen is illegal as an object key.
//
// example:
// Plug in a different easing function and register a callback for
// when the animation ends. Easing functions accept values between
// zero and one and return a value on that basis. In this case, an
// exponential-in curve.
// | dojo.animateProperty({
// | node: "nodeId",
// | // dojo figures out the start value
// | properties: { width: { end: 400 } },
// | easing: function(n){
// | return (n==0) ? 0 : Math.pow(2, 10 * (n - 1));
// | },
// | onEnd: function(node){
// | // called when the animation finishes. The animation
// | // target is passed to this function
// | }
// | }).play(500); // delay playing half a second
//
// example:
// Like all `dojo.Animation`s, animateProperty returns a handle to the
// Animation instance, which fires the events common to Dojo FX. Use `dojo.connect`
// to access these events outside of the Animation definiton:
// | var anim = dojo.animateProperty({
// | node:"someId",
// | properties:{
// | width:400, height:500
// | }
// | });
// | dojo.connect(anim,"onEnd", function(){
// | console.log("animation ended");
// | });
// | // play the animation now:
// | anim.play();
//
// example:
// Each property can be a function whose return value is substituted along.
// Additionally, each measurement (eg: start, end) can be a function. The node
// reference is passed direcly to callbacks.
// | dojo.animateProperty({
// | node:"mine",
// | properties:{
// | height:function(node){
// | // shrink this node by 50%
// | return dojo.position(node).h / 2
// | },
// | width:{
// | start:function(node){ return 100; },
