class HMdcHitAux: public HRecObject

_HADES_CLASS_DESCRIPTION

An HMdcHitAux is a segment in a mdc module.
Basically, it has a point and two slopes and the corresponding
errors. It also keep track of the calibrated hits that belong
to the segment.
It has the following functions:
- a default constructor
- a copy constructor
- a default destructor
  - addCal(HMdcCal3* data): add a pointer to the calibrated
data passed as argument to the segment.
The pointer to the calibrated hit will be stored in
the HMatrixCategory, and the number of hits in the
segment increased by one.
  - addCal(HMdcCal3* data, Int_t pos):add the calibrated data
           passed as argument to the segment in the position pos
pos is an integer between 1 and 6, corresponding to
the six planes in a mdc module.
The calibrated hit will be stored in the HCategory,
the number of hits in the segment is increased only
if ...
- print(ostream &file):prints the segment information to file
  - printCal():prints the calibrated hits to the standard output
- operator=
- markHits(void):increments the flag of all the hits in the
segment
- unMarkHits(void):decrements the flag of all the hits in the
segment
