a few minor mods
changes to make the correction function more effecient, also switched floating point elements of the CorrectionPoint structure to double type from float type
Added ability to change between angle slices of a given run.
Added support for using peak find instead of fitting peaks.
Added support to take either peak fits or finds and place the results into a TGraph2D where the x-axis is the old excitation energy, the y-axis is the angle, and z-axis is the difference between the correct excitation energy and the old excitation energy.
Unfinished support for fitting 25 term (4th order in OldEx and Angle) 2D polynomial to the TGraph2D.
