 \class AliMUONPadStatusMapMaker

 Convert a pad statuses into pad status maps.

 A pad status is one 32-bits word describing whether this pad pedestal, gains
 hv is correct or not.

 A pad status *map* is one 32-bits (of which 24 only are used)
 word describing whether this pad neighbours are ok or not
 (whether a pad is ok or not is determined by applying a given
 bitmask to the pad status word). Each bit in this word is related to one
 neighbour, assuming the pad itself is at bit 0

 ----------------
 |  3 |  5 |  8 |
 ----------------
 |  2 |  0 |  7 |
 ----------------
 |  1 |  4 |  6 |
 ----------------

 Note that for instance in NonBending plane of slats, at the boundaries
 between two pad densities, the pictures is a bit different, e.g.
 (bits in () are always zero)

 so some care must be taken when designing a mask to be tested ;-) if you
 want to go farther than immediate neighbours...

 If a pad is at a physical boundary, is will for sure have some bits at 1
 (i.e. a non-existing neighbour is considered = bad).


 add something about the reject list/probabilities here... (LA)
