+// This class allows to obtain Q_inv correlation function with weights
+// calculated by Lednicky's alghorithm.
+// Numerator is filled with weighted events. Weights are attributed to reconstructed tracks.
+// Weights are calculated with corresponding simulated particles momenta.
+// Denominator is filled with mixing unweighted reconstructed tracks.
+// One needs both pairs 
+// (simulated and recontructed), thus function is of class AliHBTTwoPairFctn1D.
