- Added ComponentInstance::receive_erased_entites() and related methods to store information about which rule generated the shape.
- Added Merge::remove_rule(shape) method which handles erasing shapes which were generated with Merge object. Replace still needs to be done!
- Controller::remove_shape changed so that it handles rules which have remove_rule methods implemented differently that those who do not.
- Improved initialization of shapes if they are on hidden_layer.
- Added UI_Menu::add_context example method, to add some shortcuts to context menu when apply or remove rule methods can be executed. Context should be developed further!
