// As the Digits and SDigits have so much in common, the classes
// AliFMDDigit and AliFMDSDigit are implemented via a base
// class AliFMDBaseDigit.

// (Note, that I'd really would have liked to implement AliFMDHit as a
// derived class from some base class - say AliFMDStrip, and the Digit
// classes would (eventually) have derived from that as well.
// However, ROOT doesn't do well with multiple inheritance, so I chose
// not to anyway).
