Removed some commented out code
areEqual added as dependency for cross2gen_helper.cpp in Makefile
areEqual.hpp added as dependency for areEqual.cpp
iss109 test running unthreaded now
Function areEqual has a single point of exit
This makes it easier to debug
 #109: Coincidence check at both timeslice bounds.
Issue was caused by coincidence between two particles being checked
only at the beginning of each timeslice, not at the end. This has
now been corrected and error is properly reported.
 #109 Added unit test for the issue.
 #109: iss109 moved to a unit test
 #109 Fix trapping of except. for coinc. check
If exception is not properly trapped in a try-catch block
and rethrown after all threads exit, multithreaded execution
causes Matlab to segfault and die.
