 Default constructor.
 id = sub event id for which the unpacker is called
 dbg = debug flag
 consisCheck = enable consistency checking of dataword

 Copy constructor

 Destructor

 Initialization routine.
 Retrieves pointers to the following objects:
			- unpacker parameters
			- raw structure
			- address correction table
			- category for raw - level information
			- category for debug information (if requested)

 reinit function, called for every new file once.
 Creates dataword depending on data version

 This function is called for each event
 It does the unpacking of the data from the hld file into the RAW category.

 return values: always 1 (philosophy: a wrong sub event should not affect the other sub events)

 inits the container cat
 looks first whether it already exists

 to sector/module/mbo/tdc coordinates.
 Then, if available the information is stored in a new or added to an existing
 data slot of HMdcRaw
 If activated, the raw data is written by fillMdcDataWord()

 Define defaults for all internal variables.

 switch to disable all error messages and warnings from hmdcunpacker AND hmdcdataword
 quiet = kTRUE : messaging switch of
       = kFALSE: messages are displayed

 this function is only for debugging use!
 the decoding of the data words continue even if there is
 unconsistency in the datawords
 cont = kTRUE : continue
 cont = kFALSE: skip event

 get a free or existing slot from the HMdcRaw category
 at the location of HLocation loc
 returns the pointer to the (new) HMdcRaw object
 NULL if it couldn't be done
