//
//  Digits classes for the FMD                
//
//  Digits consists of
//   - Detector #
//   - Ring ID                                             
//   - Sector #     
//   - Strip #
//   - ADC count in this channel                                  
//
//  Digits consists of
//   - Detector #
//   - Ring ID                                             
//   - Sector #     
//   - Strip #
//   - Total energy deposited in the strip
//   - ADC count in this channel                                  
//
// 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).
