Added matrix of channel number vs energy to PropXTalk.C.  This is to quickly check the gain matching.
Added energy threshold to filling of spectra in CoincEff().
Energy threshold now configured from LoadDefaultSettings() rather than #define.
Charge threshold also added but not used yet.
Some changes to comments and reorganising.
More settings moved to LoadDefaultSettings() rather than #define
Event limit now printed back if entered from CLI.
Bugs. Omissions from previous commit when I worked on the way the waveform samples was handled.
Changed CoincEff() arrays to work on double index [Clover][Crystal] rather than [(Clover*4) + Crystal].
Indentation and other whitespace redone.
Improved fitting of 1332 peak for efficiency evaluation:
   - now includes flat background
   - startes with more reasonable approximate guesses
Fixed some logic errors in coincidence gating.
Noticed value for flat background was not passed from Calib() fitter to FitRes struct.  Fixed.
Other minor tweaks I noticed while working on this.
