		+	The purpose of this C file is to calibrate an uncalibrated spectroscopy measurement using a nonuniform binning method subject to the energy calibration.
		+
		+	This C file will require a dat file in the form of 3 rows and 2 columns where column 1 is the channel number for a certain peak and the 2nd column is the energy in KeV of that photon peak.
		+
		+	Currently the dat file is called under the file name "temp.dat" but this can be changed.

 * Fill the array with values for bin edges using the energy calibration fit for HPGe detector. I used ''i*i'' here instead of ''i<sup>2</sup>(i**2)'' because the ROOT interpreter doesn't seem to enjoy proper math formulation.
