/*! \class   TTCluster
 *  \brief   Class to store the L1 Track Trigger clusters
 *  \details After moving from SimDataFormats to DataFormats,
 *           the template structure of the class was maintained
 *           in order to accomodate any types other than Phase2TrackerDigis
 *           in case there is such a need in the future.
