/**
* S4 Calibration Quick Look
* Author Marcelli-Malvezzi
* Version 1.00 - 27 February 2006
*
* Description: The aim of S4 Calibration QL software is to keep under control the bahaviour of S4 Calibration.
*              It creates only one output canvas relative to the time behaviour of collected calibration data.
*              See documentation for a more detailed description of the output.
*
* Parameters:
* 	       TSTring base    - the path to the root directory for the specific Pamela unpack session
*                         There is no default value, without this input the program will not run
*              TString outDir  - the path where to save the output image (Default = ./) 
*              TString format  - the format which will be used fo rsave the produced images (Default = "jpg") 
*
*
* Version 1.1 - June 2006
* Fixed bugs: for a large namber of events is not possible to initialize vectors, so all graphs have been converted in histograms
*
* Known bugs: it is no possible to choise the figure format
*
* Version 1.2 - August 2006
* Fixed bugs: is possible to choise figure format; all calibration are drown
