Integrated ScintPlane and ScintillationPaddle into old code

Now can work GetVariables for just planar scints, changing locations, variables etx. Also add in PMT # options, paddle number options, etc. Get things out of hard coding and into dynamic variables.
Inputted optional scint plane rotation and first crack at GetVar class

Now can have 1 or 2 PMTs on scint paddle (though 1 does not plot events correctly). Can have horizontal or vertical scintillator paddles to make a plane, although hit arrows need to be fixed for vertical, as well as sizes, labels. First attempt at getting GetVariables class working. Seems to be ready to go, although some errors (could not compile). Error with string declaration. Currently set up to read in from HMS.txt file to get option for 1 or 2 PMTs.
added more headers in an attempt to get strings working
