/// \class AliMUON2DStoreValidator
///
/// Determine which channels, manus, DEs, stations are missing
/// from a VStore, which must be 2D, and the 2 dimensions must be
/// (detElemId,manuId).
/// This is mainly to be used during (shuttle) preprocessing
/// to insure that what we'll put in the CDB is as complete as possible,
/// and to detect possible problem.
///
/// We made an effort to present the result of the validation in the most
/// concise way (i.e. if all channels of a DE are missing, we do not list 
/// them, we just write "DE dead" ;-) )
/// 
/// The list of missing things is kept in a structure of objects defined as :
/// 
/// fMissing = TObjArray[0..N tracking chambers]
///
/// fMissing[iChamber] = AliMUONCheckItem which contains n AliMUONCheckItem, 
/// where n is the number of DE for that chamber
///
/// fMissing[iChamber]->GetItem(de) = AliMUONCheckItem which contains m
/// AliMUONCheckItem where m is the number of Manu for that DE
///
/// fMissing[iChamber]->GetItem(de)->GetItem(manu) = AliMUONCheckItem which 
/// contains k TObjString = Form("%d",manuChannel)
