There are basically 3 types of resources that this class can handle. The first 2 are script files and a code string. The third one is a genereal object described by an XML element and in this case an object is created using a<code><a href="BiXmlResourceParser.html">BiXmlResourceParser</a></code>.<br>				<br>		 When creating general objects a few special rules apply. If the created object is an event target the resource loader will listen to <code>load</code> and <code>error</code> events so that it can be notified by the object that it is loaded. If the object has a <code>load()</code> method that will be called if the object is not already loaded. To decide if the object is loaded the resource loader will use <code>getLoaded()</code> if available and if that isn't available it is assumed that the object is loaded (or does not require loading).</p><p>This class extends		<code><a href="BiEventTarget.html">BiEventTarget</a></code>		and therefore all methods and fields available for		<code><a href="BiEventTarget.html">BiEventTarget</a></code>		are also available for <code>BiResourceLoader</code>.</p><ul class="partial-class-tree"><li><code><a href="BiObject.html">BiObject</a></code><ul><li><code><a href="BiEventTarget.html">BiEventTarget</a></code><ul><li><code>BiResourceLoader</code><ul id="api-derived-classes"></ul></li></ul></li></ul></li></ul><h2>Constructor</h2><p><code>	new BiResourceLoader()</code></p><h3>Parameters</h3><p>No parameters.</p><h2>Properties</h2><table><thead><tr><td>Name</td><td>Type</td><td class="get-header">get</td><td class="set-header">set</td><td>Descripton</td></tr></thead><tbody><tr><td><a name="autoNameMapping"></a><code>autoNameMapping</code></td><td><code class="type">Boolean</code></td><td class="get-column"><img src="check.png" alt="checked"></td><td class="set-column"><img src="check.png" alt="checked"></td><td>When this is true any XML object that has an id attribute will create a global reference to the object created from this XML element.</td></tr><tr><td><a name="count"></a><code>count</code></td><td><code class="type">Number</code></td><td class="get-column"><img src="check.png" alt="checked"></td><td class="set-column"></td><td>The number of added resources</td></tr><tr><td><a name="loaded"></a><code>loaded</code></td><td><code class="type">Boolean</code></td><td class="get-column"><img src="check.png" alt="checked"></td><td class="set-column"></td><td>Whether all resources have been loaded.</td></tr><tr><td><a name="loadedCount"></a><code>loadedCount</code></td><td><code class="type">Number</code></td><td class="get-column"><img src="check.png" alt="checked"></td><td class="set-column"></td><td>The number of finished loading resources.
