		Creates a new [name].
		
		Properties
		Methods
		[method:null load]( [page:String objUrl], [page:String mtlUrl], [page:Function onLoad], [page:Function onProgress], [page:Function onError] )
		
		[page:String objUrl] — required. URL to the .obj resource
		[page:String mtlUrl] — required. URL to the .mtl resource
		[page:Function onLoad] — Will be called when both resources load complete. The argument will be the loaded [page:Object3D].
		[page:Function onProgress] — Will be called while both load progress. The argument will be the XmlHttpRequest instance, that contain .[page:Integer total] and .[page:Integer loaded] bytes.
		[page:Function onError] — Will be called when load errors.
		
		
		Begin loading from urls and call onLoad with the parsed response content.
		
		[method:Object3D parse]( [page:String text], [page:Function mtllibCallback] )
		
		[page:String text] — required. The textual obj structure to parse.
		[page:Function mtllibCallback] — optional. Callback to handle mtllib declaration.
		
		
		Parse an obj text structure and return an [page:Object3D].
		Found objects are converted to a [page:Mesh] and materials are converted to [page:MeshLambertMaterial].
		
		Example
		
		// instantiate a loader
		var loader = new THREE.OBJMTLLoader();
		// load an obj / mtl resource pair
		loader.load(
			// OBJ resource URL
			'obj/male02/male02.obj',
			// MTL resource URL
			'obj/male02/male02_dds.mtl',
			// Function when both resources are loaded
			function ( object ) {
				scene.add( object );
			},
			// Function called when downloads progress
			function ( xhr ) {
				console.log( (xhr.loaded / xhr.total * 100) + '% loaded' );
			},
			// Function called when downloads error
			function ( xhr ) {
				console.log( 'An error happened' );
			}
		);
