Cleaned up the Binning set up for the CF spectrum.  Removed the hard coded 70s.
Fixed small bug in with the binning that was cutting of the highest energy bin.
Array CFBins is now 72 long and the number specified in the histogram constructors is
now 71 not 70.  Added error bars to the subracted TOF energy spectrum.  Built the data
and it looks like the error bars make sense.  Explictly checked the first bin and
the answer is correct.

Removed the scalled energy and the variable threshold stuff
Added error bars to subracted plots
Fixed the bug found that caused the Liquid scintillator specta to look better then before.
Had the '}' for the pulse shape discrimiation close before the random spectra construction.
So the random background did not have pulse shape discrimination in it.

Changed the error subtraction to just call SetBinError instead of making and array for the
errors
