ClearColumnElement Method

Will be called on all column element instances—both in the viewport and in the recycling pool. This is the time, if required, to undo was was done in PrepareColumnElement (e.g., unregister from events to prevent memory leaks). At this point, the reference to the element will be destroyed and the garbage collector will take care of releasing any allocated memory.
