   * Usage:

   * 	-	Add objects you would otherwise pass as 'root' to the

   *
   * 	-	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.

   * Such implementation will help you to make volumed shapes that have their own depth and can be seen from all angels.<br/><br/>
   * You can also find some interesting examples made using <a href='threejs.org'>three.js</a> which is a core of whs.js, such as:
   * - <a href='http://threejs.org/examples/webgl_geometry_extrude_shapes.html'>Webgl geometry extrude</a>

   * - <a href='http://threejs.org/examples/webgl_geometry_extrude_splines.html'>Extrude splines</a>
   *
   * Such examples can be easily implemented using whitestorm.js or it's plugins. Use `Extrude` class with <a href='https://threejs.org/docs/#api/extras/core/Shape'>THREE.Shape</a> to get extrude effect of shape defined by 2D vectors.
   * This class is similar to <a href='https://threejs.org/docs/#api/geometries/ExtrudeGeometry'>THREE.ExtrudeGeometry</a>,

   * @class Lathe
   * @category components/meshes
   * @description A `LatheGeometry` allows you to create shapes from a smooth curve.
   * This curve is defined by a number of points (also called knots) and is most often called a spline. This spline is rotated around a fixed point and results in vase- and bell-like shapes.<br/><br/>
   * In 3D computer graphics, a lathed object is a 3D model whose vertex geometry is produced by rotating the points of a spline or other point set around a fixed axis.
   * The lathing may be partial; the amount of rotation is not necessarily a full 360 degrees.
   * The point set providing the initial source data can be thought of as a cross section through the object along a plane containing its axis of radial symmetry. <br/><br/>
   * The <a href='http://threejs.org/docs/scenes/geometry-browser.html#LatheGeometry'>following example</a> shows a geometry which can be generated using `Lathe` class.
