+// AliITSTrackleterSPDEff - find SPD chips efficiencies by using tracklets.
+//
+// This class has been derived from AliITSMultReconstructor (see
+// it for more details). It is the class for the Trackleter used to estimate
+// SPD plane efficiency.
+// The trackleter prediction is built using the vertex and 1 cluster.
+
+//
