class AliFemtoBPLCMS3DCorrFctn: public AliFemtoCorrFctn


AliFemtoBPLCMS3DCorrFctn: a class to calculate 3D correlation
for pairs of identical particles.
It also stored the weighted qinv per bin histogram for the coulomb
correction.
In analysis the function should be first created in a macro, then
added to the analysis, and at the end of the macro the procedure to
write out histograms should be called.
