B2LcLc run1and2

This AP is to produce the real data as well as the MC samples for B0/Bs -> Lc Lcbar decays. This is an ongoing analysis in RC stage but a set of new DTF variables need to be introduced, so we would like to require a higher priority.

For simulation, both the signal decays B0/Bs -> Lc Lcbar and thee B0/Bs -> Lc pKpi (only one Lc) decays are produced, the latter one are used to study the lineshapes of the huge contribution from the single-charmed contribution.
