 *
 * Description: Class to provide clustering hints for StEvent I/O.
 *              The class can distinguish between two modes
 *              miniDST and DST mode in which clustering hints
 *              are different.
 *              With clustering hints we mean the association
 *              of a class stored *directly* in the StEvent class
 *              (StEvent::mContent) and the name of the branch it
 *              will be written to.
