/**
* 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:
* const 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 { .... }
* const 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:
*
* const mesh = new THREE.Mesh( geometry, material );
*
* For example:
*
* const materials = [];
* const nGeometryGroups = geometry.groups.length;
*
* const colorMap = ...; // Some logic to index colors.
*
* for (let i = 0; i < nGeometryGroups; i++) {
*
* const material = new THREE.MeshPhongMaterial({
* color: colorMap[i],
* wireframe: false
* });
*
* }
*
* materials.push(material);
* const mesh = new THREE.Mesh(geometry, materials);
