changes made to 2adf00fc901669567710b400652e60a844266c4b.
Reduced outer collimator in sculpted geometry to reduce rate
Add in headers to allow compilation without GUI
Pion polarities were reveresed
Updated default values for beam current, QWe radiative effects included
Change example to 75uA as well
Missing factor of energy in pion volume space
Faster integral method, respond to energy ranges

Merge branch 'master' of solid.physics.umass.edu:remoll
Remove very small angle scatters in Moller (nonphysical)
Add in correlated beam th, ph with x,y parameters
updated C12 generator so that it is only Mott crsec now. also updated TrackReconstruct.cc to reflect the theta_rec eqns for the updated C12 generator
Configured for 4 GEM setup. Used to be 3 GEM setup.
Fixed an error in remollMessenger that was preventing the use of targetlen, targetpos to specify target length, position from .mac file
Back to LH2 target from C12
Removed unnecessary '-->' from .gdml files. Modified 'targlen' to 'targpos' in the Messenger. Both the target length and target position modifiers were labelled 'targlen' before modification.
Modified .so to .dylib in rootlogon.C for mac
Add collimator cuts such that events from det200_r<0.03m or det201_r<0.05m do not make it to the dets
Added hit.ph variable. This is local phi at the det.
Added variable hit.colCut to flag events coming from the inner radius of collimators #2(det200) and #4(det201). Using hit.colCut==1 gets rid of these inner coll events. Dropped explicit cut for these events from the inner coll radii, which I had implemented earlier.
