BPHY18 update: allow both charge combinations, added re-vertex for di-meson.
An update needed for the background studies and NN training in the R(K*) analysis. Changes:
- di-electron: opposite charge combination only -> all charge combination allowed,
- di-meson (K* candidate): opposite charge combination only -> all charge combination allowed,
- new container with re-vertexed di-meson (no cascade decay, only a separate vertex fit for the 2 previously selected tracks).
Changes tested locally (small samples of MC and DATA AODs) and on GRID (one signal MC, one background MC, one DATA run).
