[151] Update the output log message of the evaluation script

This enumerates the currently implemented constraints in a clearer way.
Furhermore all the possible paths within the graph are not added to the
output log message anymore. Basically it is just checked whether the
paths end in a StopEvent or not. If not, for this specific end node in
the graph a particular message is being printed out.
Merge branch 'feature-151' into develop
