Refactor controller: extract component for managing dispatching front,
...
drop Store, introduce ProcessingState and StateFrame.
ProcessingState class to represent current state, including the
dispatching front and all the logical observers.

and launches processing via Controller.
Breaking change: the frames correspond to an activated constraint occurrence,
and not to a triggered rule match as it has been the case before.
