Draft: B2llX_mvabased line for B+ -> K ee/mumu
HLT2 lines for B+-> LLX decays, including eeK and mumuK. The selections are based on the current B2LLXBDT stripping lines.
Included modes: 1.B+ -> e+ e- K+ 2.B+ -> mu+ mu- K+
To be done: Other decays are in progress. MVA cuts will be updated with new ThOr functors. Hlt efficiency check will be done after selections are all ready.
