[CMAKE] Added the 'inc' folder to include direcotries

This fixes the problem in qtcreator that it complains about missing
includes and can't jump to these files when you click them or methods
defined in there.
Fixed helicity usage in GoAT, now using same nomenclature as in TA2GoAT
Fixed error in GTreeTrigger in setting branch addresses for ErrModIndex and ErrCode. Both had a random period in the name, causing them to not load
Added centralCrys and centralVeto read/write into GoAT. Also added method GetClusterSize without index to return whole array, similar to others
Added NaI_Cluster and BaF2_PbWO4_Cluster read/write into GoAT
Added a quick cluster drawing macro. Created macro directory as temporary placeholder for it, though hopefully will incorporate this into compiled code in the near future
Adjusted Fill methods to properly handle simple Fill(value) calls to both prevent unwanted tagger dependence and allow for time cuts where the prompt cut does not encompass zero
Edited DrawCluster to encompass the x and y of TAPS in the 3D plot
TH2 also included!
Virtual Write routine
Increased max scaler from 4096 to 16384
Robust LinPol Tree
Added TH1s back to PPhysics
Added generic routine to PPhysics for summing scalers
Added Scaler read for ppi0 example, includes TH1 readout
Why not add TH3s as well
