Detailed Description

class EmcBhaCalib Algorithm - performs calibration of EMC Xtals with Bhabha events and Chi^2 fit, the resulting system of linear equations of the fit is solved with the SLAP Algebra package

The matrix and the vector can either be fetched from file(s). If they are read from files the file names are supposed to have the name CalibVector.dat and calibMatrix.dat with an extension at the beginning. Only these extensions (usually the runnumbers) need to be listed in the read-in-file that is specified with runNumberFile.
