 Derived classes must implement these two functions: OnPgmInit() and
 OnPgmExit(), and since they are only called from same source file as their
 implementation, these need not be virtual here. In fact, in the case of
 python project manager's class PGM_PYTHON, these functions are actually
 written in python. In total there are three implementations, corresponding
 to the three defines given by kiface.h's KFCTL_* #defines.
