// steal is a resource loader for JavaScript.  It is broken into the following parts:
//
// - Helpers - basic utility methods used internally
// - AOP - aspect oriented code helpers
// - Deferred - a minimal deferred implementation
// - Uri - methods for dealing with urls
// - Api - steal's API
// - Resource - an object that represents a resource that is loaded and run and has dependencies.
// - Type - a type systems used to load and run different types of resources
// - Packages -  used to define packages
// - Extensions - makes steal pre-load a type based on an extension (ex: .coffee)
// - Mapping - configures steal to load resources in a different location
// - Startup - startup code
// - jQuery - code to make jQuery's readWait work
// - Error Handling - detect scripts failing to load
// - Has option - used to specify that one resources contains multiple other resources
// - Window Load - API for knowing when the window has loaded and all scripts have loaded
// - Interactive - Code for IE
// - Options -

		 * Registers a type.  You define the type of the file, the basic type it
		 * converts to, and a conversion function where you convert the original file
		 * to JS or CSS.  This is modeled after the
		 * [http://api.jquery.com/extending-ajax/#Converters AJAX converters] in jQuery.
		 *
		 * Types are designed to make it simple to switch between steal's development
		 * and production modes.  In development mode, the types are converted
		 * in the browser to allow devs to see changes as they work.  When the app is
		 * built, these converter functions are run by the build process,
		 * and the processed text is inserted into the production script, optimized for
		 * performance.
		 *
		 * Here's an example converting files of type .foo to JavaScript.  Foo is a
		 * fake language that saves global variables defined like.  A .foo file might
		 * look like this:
		 *
		 *     REQUIRED FOO
		 *
		 * To define this type, you'd call steal.type like this:
		 *
		 *     steal.type("foo js", function(options, original, success, error){
		 *       var parts = options.text.split(" ")
		 *       options.text = parts[0]+"='"+parts[1]+"'";
		 *       success();
		 *     });
		 *
		 * The method we provide is called with the text of .foo files in options.text.
		 * We parse the file, create JavaScript and put it in options.text.  Couldn't
		 * be simpler.
		 *
		 * Here's an example,
		 * converting [http://jashkenas.github.com/coffee-script/ coffeescript]
		 * to JavaScript:
		 *
		 *     steal.type("coffee js", function(options, original, success, error){
		 *       options.text = CoffeeScript.compile(options.text);
		 *       success();
		 *     });
		 *
		 * In this example, any time steal encounters a file with extension .coffee,
		 * it will call the given converter method.  CoffeeScript.compile takes the
		 * text of the file, converts it from coffeescript to javascript, and saves
		 * the JavaScript text in options.text.
		 *
		 * Similarly, languages on top of CSS, like [http://lesscss.org/ LESS], can
		 * be converted to CSS:
		 *
		 *     steal.type("less css", function(options, original, success, error){
		 *       new (less.Parser)({
		 *         optimization: less.optimization,
		 *         paths: []
		 *       }).parse(options.text, function (e, root) {
		 *         options.text = root.toCSS();
		 *         success();
		 *       });
		 *     });
		 *
		 * This simple type system could be used to convert any file type to be used
		 * in your JavaScript app.  For example, [http://fdik.org/yml/ yml] could be
		 * used for configuration.  jQueryMX uses steal.type to support JS templates,
		 * such as EJS, TMPL, and others.
		 *
		 * @param {String} type A string that defines the new type being defined and
		 * the type being converted to, separated by a space, like "coffee js".
		 *
		 * There can be more than two steps used in conversion, such as "ejs view js".
		 * This will define a method that converts .ejs files to .view files.  There
		 * should be another converter for "view js" that makes this final conversion
		 * to JS.
		 *
		 * @param {Function} cb( options, original, success, error ) a callback
		 * function that converts the new file type to a basic type.  This method
		 * needs to do two things: 1) save the text of the converted file in
		 * options.text and 2) call success() when the conversion is done (it can work
		 * asynchronously).
		 *
		 * - __options__ - the steal options for this file, including path information
		 * - __original__ - the original argument passed to steal, which might be a
		 *   path or a function
		 * - __success__ - a method to call when the file is converted and processed
		 *   successfully
		 * - __error__ - a method called if the conversion fails or the file doesn't
		 *   exist

	// ============ RESOURCE ================

	// created - the steal instance is created, but we haven't started loading it yet
	//           this happens when thens are used
	// loading - (loading=true) By calling load, this will tell steal to load a file
	// loaded - (isLoaded=true) The file has been run, but its dependency files have been completed
	// complete - all of this files dependencies have loaded and completed.


	// A Resource is almost anything. It is different from a module
	// as it doesn't represent some unit of functionality, rather
	// it represents a unit that can have other units "within" it
	// as dependencies.  A resource can:
	//
	// - load - load the resource to the client so it is available, but don't run it yet
	// - run - run the code for the resource
	// - executed - the code has been run for the resource, but all
	//   dependencies for that resource might not have finished
	// - completed - all resources within the resource have completed
