*
* 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.
