/**
 * This class is the conversion of the Pose channel constraint.
 * It makes a link between the pose constraint and the KX scene.
 * The main purpose is to give access to the constraint target 
 * to link it to a game object. 
 * It also allows to activate/deactivate constraints during the game.
 * Later it will also be possible to create constraint on the fly
