* Updates on pion detector studies (Elham)
** standalone simulations for photo-electron optimization
*** incoming electrons perpendicular to face of detector
*** need to avoid double-counting pions that penetrate through all planes, but not for 2 MeV electrons which range out in the first plane
*** changes to lucite outside width are having more effect on pion light collection efficiency than electron light collection efficiency due to more isotropic behavior of electrons when ranging out
*** TODO: rotate entire lucite detector by angles up to 90 degrees to see the impact for electrons coming in from other angles
** different showermax position (closer to the lead donut) and shifted in radius
*** baseline comparison is different from earlier, maybe due to shift of downstream showermax already being applied?
** hits time ordering
*** why are there so many photon hits in the front face compared to the back photons?
*** maybe the hits in the front face are mulitple-counted due to the glue layer?
*** TODO: produce listing of times when photons arrive
*** TODO: run a standalone simulation with glue index of refraction set to 1
