//  Class for trigger analysis.
//  Digits are grouped in TRU's (384 cells ordered fNTRUPhi x fNTRUEta). 
//  The algorithm searches all possible 2x2 and nxn (n is a multiple of 4) cell 
//  combinations per each TRU,  adding the digits amplitude and finding the 
//  maximum. Maxima are compared to triggers threshold and they are set. 
//  Thresholds need to be fixed. Last 2 modules are half size in Phi, I considered 
//  that the number of TRU is maintained for the last modules but decision not taken. 
//  If different, then this must be changed.
