[Halld-offline] Instructions for removing charged interactions from list of photons

[Matthew Shepherd]

Hi Elton,

I believe Blake's better algorithm for suppressing charged particles in the list of photons has been checked in now and can be used.  You should update your code and rebuild.

I've written brief documentation for how to get photons and pi0^s for use in analysis.  It is posted on the Offline Software Wiki here:

http://www.jlab.org/Hall-D/software/wiki/index.php/HOWTO_extract_photons_or_pi0%27s_from_the_framework

Please try this, and if you have any questions let us know.  If you find parts of the documentation not quite clear, feel free to correct or append to it.

Cheers,

Matt
