//  Class for trigger analysis.
//  Digits are grouped in TRU's (16x28 crystals). The algorithm searches 
//  all possible 4x4 crystal combinations and per each TRU, adding the 
//  digits amplitude and finding the maximum. Maximums are compared to 
//  triggers threshold and they are set.
//  FIRST ATTEMPT TO MAKE A TRIGGER CLASS. IT WILL CHANGE WHEN CENTRAL TRIGGER CLASS FIXES 
//  THINGS
