This class produces a 3d histogramms containing the momentum resolution correction. The measred correlation function
should be multiplied with this histogramm to get the momentum.
This class fills takes as input particle lists. It combines pairs and fills four histogramms,
ideal signal distbritution (pairs are weight according to BE and coulomb), ideal background (weight =1)
and smeared signal and background. The smearing is either done by default momentum resolution or by
resolution obtain from Monte Carlo (provided via the T49HbtMomentumResolutionProvider class).

Make sure we get two differen lists ! We need to use the uncorrelated background.
