/////////////////////////////////////////////////////////////
//  HMdcLookupRaw
//
//  Container class for lookup parameters to map the
//  geometrical tree of the Mdc (sectors, modules, layers,
//  cells) to the hardware tree of the Mdc (sectors, modules,
//  motherboards, TDC channels).
//  This information is needed for data mapping from cal1
//  level to raw level.
//  This container has no read functions in the I/O classes,
//  but is initialized from the lookup table HMdcLookupGeom,
//  which contains the same information but accesssible with
//  hardware addresses. This garanties the consistency when
//  both containers are needed.
//  A write function is only privided for an Ascii I/O.
