// MUON Raw Data generator in ALICE-MUON
//
// This class version 1 (further details could be found in Alice-note coming soon right in our direction)
// Generates raw data for MUON tracker and finally for trigger
// * a simple mapping is used (see below)
// * the bus patch id is calculated with an absolute number 0 - 999
// * one DDL per 1/2 chamber is created for both cathode.
// For trigger there is no mapping (mapping could be found in AliMUONTriggerCircuit)
// don't need for digits2raw but needed in raw2Reco
// the position are given per local card
