17/// \class AliMUONPadStatusMapMaker
18///
19/// Convert a pad status container into a pad status *map* container
20///
21/// A pad status is one 32-bits word describing whether this pad pedestal, gains
22/// hv is correct or not.
23///
24/// A pad status *map* is one 32-bits (of which 24 only are used)
25/// word describing whether this pad neighbours are ok or not
26/// (whether a pad is ok or not is determined by applying a given
27/// bitmask to the pad status word). Each bit in this word is related to one
28/// neighbour, assuming the pad itself is at bit 0
29///
30/// ----------------
31/// | 3 | 5 | 8 |
32/// ----------------
33/// | 2 | 0 | 7 |
34/// ----------------
35/// | 1 | 4 | 6 |
36/// ----------------
37///
38/// Note that for instance in NonBending plane of slats, at the boundaries
39/// between two pad densities, the pictures is a bit different, e.g.
40/// (bits in () are always zero)
41///
42/// so some care must be taken when designing a mask to be tested ;-) if you
43/// want to go farther than immediate neighbours...
44///
45/// If a pad is at a physical boundary, is will for sure have some bits at 1
46/// (i.e. a non-existing neighbour is considered = bad).
