[sequencechart] implemented functionality to- write event duration into eventlog- measure event complexity- write event complexity into eventlog- parse complexity in eventlog interface from ievent java JNI
- added EventEndEntry into eventlog data format
[eefscheduler] added changes from codereview (minor stuff) and moved scheduler call again from cSimulation to Tkenv and Cmdenv respectively
[eefscheduler] restructured doOneEvent-doOneEvent now has no parameter-getNextEvent now removes elements from the FES/IES-still getting deadlock when IES runs empty
Initial import of Horizon 4 release.
