23//
24// Digits classes for the FMD
25//
26// Digits consists of
27// - Detector #
28// - Ring ID
29// - Sector #
30// - Strip #
31// - ADC count in this channel
32//
33// Digits consists of
34// - Detector #
35// - Ring ID
36// - Sector #
37// - Strip #
38// - Total energy deposited in the strip
39// - ADC count in this channel
40//
41// As the Digits and SDigits have so much in common, the classes
42// AliFMDDigit and AliFMDSDigit are implemented via a base
43// class AliFMDBaseDigit.

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