//_HADES_CLASS_DESCRIPTION 
///////////////////////////////////////
//HldUnpack
//
//  ABC for the different unpackers.
//
//  The unpackers are used to unpack the data from Lmd files and put them
//  into the HEvent structure.
//
//  The job of an unpacker starts when its execute function is called within
//  HLmdSource::getNextEvent(), in this function the unpacker reads data from
//  an HldEvt (corresponding to an event as stored by the data adquisition 
//  system) and extracts the info to the category pRawCat.
