Step 1: Configure Event generator in which electron parameters can be changes. Move the source left and right of the center. Change is momentum direction; going left and going right.
Step 2: comment out electron and add gamma. get it to move in the same way.
Step 3: turn them both on
Step 4: if fail then find references on event Generator with 2 intersecting beams, perhaps ILC, LHC or BaBar has one.

Problem last week was due to editing the wrong file.
We now have a event generator which starts an electron and a photon moving toward eachother.
We see and event when the photon energy is 500 keV and only the compton process is turned on.
Next step:
1.) edit the Stepping Verbose so only a Compton event is printed out
2.) add an event counter so we know how many beam triggers are done to get the event( edit SteppingVerbose.h, add a global variable to the class definition)
3.) Insert new physics process for Low Energy Compton
