//This is the implementation of the (virtual) base class for the FMD detector 
//algorithms(DA). It implements the creation of the relevant containers and handles the 
//loop over the raw data. The derived classes can control the parameters and action
//to be taken making this the base class for the Pedestal, Gain and Physics DA.
