* @author aleeper / http://adamleeper.com/

*
* 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 );
