-/**<strong>This control is still a WIP, use it at your own risk</strong><br>
- * To use this control you need a model with an AnimControl and a SkeletonControl.<br>
- * This should be the case if you imported an animated model from Ogre or blender.<br>
- * Note enabling/disabling the control add/removes it from the physic space<br>
- * <p>
- * This control creates collision shapes for each bones of the skeleton when you call spatial.addControl(ragdollControl).
- * <ul>
- *     <li>The shape is HullCollision shape based on the vertices associated with each bone and based on a tweakable weight threshold (see setWeightThreshold)</li>
- *     <li>If you don't want each bone to be a collision shape, you can specify what bone to use by using the addBoneName method<br>
- *         By using this method, bone that are not used to create a shape, are "merged" to their parent to create the collision shape.
- *     </li>
- * </ul>
- *</p>
- *<p>
- *There are 2 modes for this control : 
- * <ul>
- *     <li><strong>The kinematic modes :</strong><br>
- *        this is the default behavior, this means that the collision shapes of the body are able to interact with physics enabled objects.
- *        in this mode physic shapes follow the moovements of the animated skeleton (for example animated by a key framed animation)
- *        this mode is enabled by calling setKinematicMode();                
- *     </li>
- *     <li><strong>The ragdoll modes :</strong><br>
- *        To enable this behavior, you need to call setRagdollMode() method.
- *        In this mode the charater is entirely controled by physics, so it will fall under the gravity and move if any force is applied to it.
