*This example shows how one can obtain the cluster size
*distribution for tracks generated by the Heed program.
*Since Heed does not generate clusters but always delta
*electrons (they usually have a very short range), we use
*the NODELTA-ELECTRONS option on the TRACK command. This compresses
*the delta electrons into clusters.
