// AliTOFDigitMap class
//
// digitmap enables fast check if the pad was already digit.

// The index of a AliTOFdigit is saved in the each digitmap "cell"
// (there is an offset +1, because the index can be zero and zero
// means empty cell).
// In TOF, number of strips varies according plate type, the highest
// number is in plate C. For all plates is used this number, so the
// size of the digitmap is a little bit greater than necessary, but it
// simplifies the access algorithm.
