       The starting and finishing ends must not be the same semantic object except for StateMapping.
       
       StateMapping allows to have the same semantic element as starting and finishing end. It can be used to represent punctual/instantaneous elements. 
       It will count for a single event end in semantic and graphical orderings and will be considered for feedback during resize and move as the center of the figure repsenting the State.
