/**
* Header Scan
* Author  Nagni
* version 1.0
*
* Version 1.1 - 28 December 2004
* If outList does not exist the function exit to prompt
* If nevents = 0 the function exit to promt
*
* Version 1.2 - 3 January 2005
* Two canvases are created to see the graphs better
*
* Version 1.25 - 13 January 2005
* Changed Int_t to Float because of variable range size
* (UInt_t has been excluded beacuse of uncompatibility with TGraph)
*
* version 1.3  - 22 February 2005 - Nagni
* For compatibility with batch mode excution:
* 1) Added "include <iostream>" and "using namespace std" 
* 2) Removed gROOT->Reset()
*
* Version 1.4
* Date 08 March 2005
* Added "format" parameter for saving the produced image in various formats
* (for a complete list of types refer to TPad::SaveAs method)
*
* Version 1.5
* Date 09 February 2006 - Marcelli
* Update to work with new Yoda output
*
* Version 1.6
* Date 27 February 2006 - Marcelli
* For compilation: 
*     Added function "int main(int argc, char* argv[])"
*
*
* Description: This script creates two canvases with five pads. The first pad shows packetID variable (for all packets) vs. OBT.
*              The second pad shows the number of physic packets vs. OBT. The third pad shows the lenght of Physic packets (byte) vs. OBT.
*              The fourth pad shows the packetcounter of physic packets vs. OBT. The fifth pad shows PacketCounter vs. File Offset.
*
* 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 1.7
* Date 16 June 2006 - Malvezzi
*
* Description of changes:
*                         Implementation of the case: numebr of events <= 0.
*                         Remove graph "grPcktId1"; see PacketScan for the same information.
*             Fixed bugs: for a large namber of events is not possible to have vectors, so I have subsituted graphs with histograms
*                         or divided the graphs in more than one canvas.
