+// A histogram of flow bins.  The axis can by anything
+// (pseudo-rapidity, transvers momentum) - there's no assumption on
+// what is the basis of the histogram.  The method Event can be used
+// to calculate everything in one go.   Alternatively, one can use the
+// methods AddToEventPlane and AddToHarmonic.  See also the example
