/// \ingroup management
/// \class AliMpDEManager
/// \brief The manager class for definition of detection element types
//
/// The detection element types are defined via unique names
/// in denames.dat file for each station in the mapping data.
/// Detection element name is composed of DETypeName and planeTypeName.
/// DETypeName is only one per station in case of station1 and 2 quadrants, 
/// there are more DETypes in case of slat and trigger stations.
