Hello,
This MR is eliminating variable caching from the FeatureExtractor tool used in tau substructure reconstruction: the m_Variants_SeedEt map is now filled and used on the fly.
This unblocked the situation for all other tools, we can now have const execute methods for all PanTau tools... We still have a few const_cast.
It was the last step toward a re-entrant algorithm.
This MR does not change the reconstruction output.
Cheers, Bertrand
