//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.
