D Neise: april 2014

In this folder I want to develop some improved version of pyfact.
I would like to deal without the special python accessors, we included 
into fits.h.
Or maybe reduce them to only something like:
int GetNumberOfKeys()
string GetKey( int key_id)

In addition I would like to enhance the funcionality of 
calfactfits.h, i.e. of the CalFactFits class a bit.

Currently this class can only be constructed with a 
RawData file name and a Calibration File name, but I would like to 
be able to use this class as well, for working on *not* calibrated data.
Also I would like re-use the Drs calibration code from 
Mars/mcore/DrsCalib.h
instead of reimplementing it in calfactfits.h 

I currently don't really see how to re-use either the DrsCalibrate class or the 
DrsCalibration class (both implemented in Mars/mcore/DrsCalib.h)
but I'm sure there is a way.
