+// Class AliCalcluster
+// Description of a cluster of calorimeter modules.
+// A matrix geometry is assumed in which a cluster center
+// is identified by (row,col) and contains sig as signal
+// being the signal of the complete cluster.
+// Some info about cluster topology is provided in order
+// to enable EM or hadronic cluster identification.
