-// class AliHBTWeightQInvFctn
-//
-// 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.
