Cleared output vectores at the end of events to avoid re-writing data and exponentially growing output files

Removed geom.mac execution. Removed /gps/number because all photons are emitted from one point per event.

Adjusted GetEvent to read higher precision inputs to set momentum vector within 10*-9 of a unit vector

Added ability to inuput photon info from ASCII and changed tree output data type to std::vector<double>
