//   triglvl2.C
//  Macro to use the class MMcTriggerLvl2, which calculates the 
//   2nd level trigger (L2T) selection parameters.
//  Filters to select events using these parameter and 
//  histograms with selection variables distributions are also created.
//
//   Inputs:
//      - filename      name of data file
//      - CompactNN     number of NN to define a compact pixel
//      - fValue        comparision value for the filter
//
//  23/04/2003 Added example of MFEnergySlope filter
//
