Test pulse calibration

Implementation of a the test: tpcalibration

The test determines the gain to convert VCth into electrons by using internal test pulses with known charge. This is done by recording SCurves, using the PedeNoise.h class with different test pulse amplitudes. The pedestals of the test pulses are correlated with the test pulse amplitude. For each channel the gain value is extracted by fitting a first order polynomial to amplitude over pedestal. The slope of the polynomial is the gain for the channel.

The code was tested using a 2CBC3 Mini Module and resulted in a gain of about 180electrons/VCth.
