Jpsi2LmdLmdbar Run 3 MC
This MR supersedes !1668 (merged). Old ntuples can be deleted after this MR is finalised.
This AP is designed for MC tuples generation with J/psi \rightarrow \Lambda \overline{\Lambda} sample. Important bug fixes were implemented with respect to the previous version.
Two HLT1 sequences are used: hlt1_pp_forward_then_matching_and_downstream_1200KHz
and hlt1_pp_forward_then_matching_1000KHz
in order to reflect two HLT1 trigger situations (with/without downstream).
