+/**
+ * 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:
+ *	const 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'
+ * } );
+ *
+ * Custom properties outside of the defaults for position, uv, normal
+ * and color attributes can be added using the setCustomPropertyNameMapping method.
+ * For example, the following maps the element properties “custom_property_a”
+ * and “custom_property_b” to an attribute “customAttribute” with an item size of 2.
+ * Attribute item sizes are set from the number of element properties in the property array.
+ *
+ * loader.setCustomPropertyNameMapping( {
+ *	customAttribute: ['custom_property_a', 'custom_property_b'],
+ * } );

+/**
+ * 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);
