/**

* 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
