/// Efficiency is stored per cathode on local boards
///
/// The main method of this class is IsTriggered().
///
/// $ALICE_ROOT/MUON/data/efficiencyCells.dat contains efficiency 
/// for each chamber (i.e. DetElement). 
///
/// In the case of local boards, efficiency is stored from left to right
/// per increasing board number (from 1 to 234)
///
/// The file can be edited in order to change efficiency
/// in a chosen local board/region of the chamber.
