/// \class AliMpCDB
/// \brief Manager class for mapping CDB IO
///
/// The mapping can be loaded in two ways:
/// - from mapping objects stored in the CDB folders Mapping, DDLStore
///   (old way)
/// - from mapping data store in a form of string map in the CDB 
///   folder MappingData (new way, now default)
///
/// To switch between these two ways:
/// - AliMpCDB::SetLoadFromData(Bool_t);
/// 
/// Now it is also possible to regenerate mapping ASCII data
/// from the string map:
/// - AliMpCDB::GenerateMpData();
///
