  New event generator based on external file

This event generator takes a remollout.root file as input.  Why is that
useful? Simulations of the electrons getting through the Pb wall are very
slow (since now many electrons make it through). So, we have a virtual
detector that is located right after the Pb wall. We can now, once, run
a long simulation of electrons, and use that as input for optical simulations
of only the downstream pion detector system.

  Some events have no hits in the desired detector.

In those cases the virtual event generator parent class kicks out
the event because it's invalid. We should continue trying to read
events until we have at least 1 hit.
