+   *
+   * 	-	Instead pass this object as 'root'.
+   *
+   * 	-	You can also add and remove objects later when the mixer

+   *
+   * 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
