[G12] Lepton Simulation

[Michael Paolone]

Hey MK,

I'm not entirely sure how Craig did it, but here's my 2 cents. You might
need to modify your GAMP output to have a z vertex, and then modify
gamp2part to propagate that vertex into the PART bank (instead of a
randomly assigned z within the target cell).  If this is what Craig did,
he may still have his modified gamp2part.
