Worked on msg display.
Type and null check
Min MagicDraw and SysML version set to 18.3 via plugin descriptor
User guide and tutorial updated with FAS-behavior.
fixed 54 and a bug where unclear positioning wasn't detected
fixed ticket #39, added error output in GUI Log
Finished working ticket #39
continued working tickets #39 and #44, redundand creation is now reduced to twice which still should not happen
Fixed Task 024, started working ticket #44 no exceptions anymore but one of the connectors is created thrice -> needs debugging
unclear positioning now spawns one (or more) error message(s) reassignFlows counts occurrences of behaviors and connectors as basis for a solution to ticket #39, yet to be implemented
