20// AliTOFHitMap class
21//
22// hitmap enables fast check if the pad was already hit
23// The index of a AliTOFSDigit is saved in the each hitmap "cell"
24// (there is an offset +1, because the index can be zero and
25// zero means empty cell.
26// In TOF, number of strips varies according plate type, the highest
27// number is in plate C. For all plates is used this number, so
28// the size of the hitmap is a little bit greater than necessary, but
29// it simplifies the access algorithm.
