*
* A group of objects that receives a shared animation state.
*
* Usage:
*
* - Add objects you would otherwise pass as 'root' to the
* constructor or the .clipAction method of AnimationMixer.
*
* - Instead pass this object as 'root'.
*
* - You can also add and remove objects later when the mixer
* is running.
*
* Note:
*
* Objects of this class appear as one object to the mixer,
* so cache control of the individual objects must be done
* on the group.
*
* Limitation:
*
* - The animated properties must be compatible among the
* all objects in the group.
*
* - A single property can either be controlled through a
* target group or directly, but not both.

* Versions lower than this may load but will probably have errors

* Needs Support:
* Morph normals / blend shape normals

*
* 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.
*
* The loader returns a non-indexed buffer geometry.
*
* 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.
*
* Usage:
* var loader = new 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: true });
* } else { .... }
* var mesh = new THREE.Mesh( geometry, material );
*
* For ASCII STLs containing multiple solids, each solid is assigned to a different group.
* Groups can be used to assign a different color by defining an array of materials with the same length of
* geometry.groups and passing it to the Mesh constructor:
*
* var mesh = new THREE.Mesh( geometry, material );
*
* For example:
*
* var materials = [];
* var nGeometryGroups = geometry.groups.length;
*
* var colorMap = ...; // Some logic to index colors.
*
* for (var i = 0; i < nGeometryGroups; i++) {
*
* var material = new THREE.MeshPhongMaterial({
* color: colorMap[i],
* wireframe: false
* });
*
* }
*
* materials.push(material);
* var mesh = new THREE.Mesh(geometry, materials);

* @author Wei Meng / http://about.me/menway
*
* Description: A THREE loader for PLY ASCII files (known as the Polygon
* File Format or the Stanford Triangle Format).
*
* Limitations: ASCII decoding assumes file is UTF-8.
*
* Usage:
* var loader = new PLYLoader();
* loader.load('./models/ply/ascii/dolphins.ply', function (geometry) {
*
* scene.add( new THREE.Mesh( geometry ) );
*
* } );
*
* If the PLY file uses non standard property names, they can be mapped while
* loading. For example, the following maps the properties
* “diffuse_(red|green|blue)” in the file to standard color names.
*
* loader.setPropertyNameMapping( {
* diffuse_red: 'red',
* diffuse_green: 'green',
* diffuse_blue: 'blue'
* } );
*
