+ * scene.add(objecttree);
+ * });
+ *
+ * Materials now supported, material colors supported

+ * @author aleeper / http://adamleeper.com/
+ * @author mrdoob / http://mrdoob.com/
+ * @author gero3 / https://github.com/gero3
+ *
+ * Description: A THREE loader for STL ASCII files, as created by Solidworks and other CAD programs.
+ *
+ * Supports both binary and ASCII encoded files, with automatic detection of type.
+ *
+ * Limitations:
+ * Binary decoding supports "Magics" color format (http://en.wikipedia.org/wiki/STL_(file_format)#Color_in_binary_STL).
+ * There is perhaps some question as to how valid it is to always assume little-endian-ness.
+ * ASCII decoding assumes file is UTF-8. Seems to work for the examples...
+ *
+ * Usage:
+ * var loader = new THREE.STLLoader();
+ * loader.load( './models/stl/slotted_disk.stl', function ( geometry ) {
+ * scene.add( new THREE.Mesh( geometry ) );
+ * });
+ *
+ * For binary STLs geometry might contain colors for vertices. To use it:
+ * // use the same code to load STL as above
+ * if (geometry.hasColors) {
+ * material = new THREE.MeshPhongMaterial({ opacity: geometry.alpha, vertexColors: THREE.VertexColors });
+ * } else { .... }
+ * var mesh = new THREE.Mesh( geometry, material );

+ *
+ * - Instead pass this object as 'root'.
+ *
+ * - You can also add and remove objects later when the mixer

+ *
+ * Note:
+ *
+ * Objects of this class appear as one object to the mixer,

+ *
+ * Limitation:
+ *
+ * - The animated properties must be compatible among the
