class AliMpVSegmentation: public TObject

 Destructor

 Returns the list of neighbours of pad
 testPositions are the positions (L,T,R,B) relative to pad's center (O)
 were we'll try to get a neighbouring pad, by getting a little
 bit outside the pad itself.
 The pad density can only decrease when going from left to right except
 for round slates where it is the opposite.
 The pad density can only decrease when going from bottom to top but
 to be symmetric we also consider the opposite.
 The order in which we actually test the positions has some importance,
 i.e. when using this information to compute status map later on. Here's
 the sequence :
 <pre>
 4- 5- 6-7
 |       |
 3       8
 |   0   |
 2       9
 |       |
 1-12-11-10
