The MR implements the continuous "VHbb style" b/c-tagger within the FTAG central packages.
More details on the tagger and the "Continuous2D" WP: here
We tested it locally and validated the output both on ATop and the CxAODFramework.
- rename of mv2c_ variables with more generic names to avoid confusion in the future
- remove mv2c100_mv2c100 2D tagger (obsolete) where not needed.
