Class Description

                                                                      
 ATLFast MCMaker class.                                               
                                                                      
 This class generates MC events or read events from a file.           

    Clean particles array before writing to file
   if m_Save = 1 (default), save only hard scattered particles
   if m_Save = 2 save all particles (used by event display)

    Reset Cell Maker

    Add itself to the list of graphics primitives in pad

.............................................
  Initialize the Event generator
  The current implementation supports two operational modes
     A- Generation on the fly using Pythia with the following 10 modes
        1- H-->gam gam
        2- Z-->ee
        3- Z-->mumu
        4- H-->ZZ-->4e
        5- H-->ZZ-->4mu
        6- H-->ZZ-->2mu2e
        7- WH, H-->bb, W-->lnu
        8- WH, H-->gg, W-->lnu
        9- WH, H-->jj, W-->lnu
       10- bbA, A--> tau tau

    B- Read a Root Tree file previously generated with one of the modes above
      101- Read file pythia1.root with H-->gam gam events
      102- Read file pythia2.root with Z-->ee events
      .....
      110  Read file pythia10.root with bbA, A--> tau tau events

    C- Read a GENZ file
      201

   The operational mode is selected via ATLFMCMaker->SetProductionMode.

  This function generates one MonteCarlo event
  Read from a file if production mode > 100
  else generation on the fly

    Paint generated particles

   Compute phi angle of particle
 ... this is a copy of function ULANGL
  .. sign(a,b) = -abs(a) if b <  0
               =  abs(a) if b >= 0

... this is copy of function LUCHGE
...Purpose: to give three times the charge for a particle/parton.

... this is copy of function LUCOMP
...Purpose: to compress the standard KF codes for use in mass and decay
...arrays; also to check whether a given code actually is defined.
