+// As the Digits and SDigits have so much in common, the classes

+// (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).
