/*! \class   TTClusterAlgorithm
 *  \brief   Base class for any algorithm to be used
 *           in TTClusterBuilder
 *  \details After moving from SimDataFormats to DataFormats,
 *           the template structure of the class was maintained
 *           in order to accomodate any types other than PixelDigis
 *           in case there is such a need in the future.
