 *********************************************************************
 * Descripion:
 *  example algo finding list of 2x2 ETOW clusters based on ET-seed list produced by L2-etow-calib algo
 * features: uses 2D array (ieta vs. iphi )
 * Limitations:
 *   - ignores seeds at the  edges
 *   - double counts for neighbours seeds
 *   - no provision for wrap up in phi
