// This class provides a base interface for the Detector Algorithms
// (DA) of the FMD.  At least three implementations are needed:
// AliFMDPedestalDA, AliFMDGainDA and AliFMDPhysicsDA .  These classes
// will provide the calibration data for the AliFMDPreprocessor to be
// used in the shuttle.  The input for this class are raw data
// (AliRawReader) and the output is a comma-separated file
// (std::ofstream) that contains the values defined in the
// implementations of this class.
