made the correction functions divide the angle by 2, this prevents the function fit from misbehaving due to angles close to 1 degree blowing up
removed a superfluos include
added the root generated .d and .so files to the ignore file
This is the external file of functions to be used with fitting, since it does not use the GUI interface it can be loaded with ".L abFitLib.C+" instead of ".L abFitLib.C" therefore the functions are compiled and so they are much much faster in performing the fits also, this way there is little cost to resetting thing or playing around since the fit points are independant data
