+//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.
