 * This defines the adding-process of the hits from the

 * having more than one hit per station, this can be a problem
 * for the global analysis and for the following trackfitter.
 * So the defined number decides the about the adding-process:
 * 1) All hits are added.
 * 2) Just one hit per layer is added, which occurs most
 *    frequently.
 * 3) The hit per layer is added, which occurs most frequently.
 *    If there are more hits with the same frequence, all of
 *    these are added.
