Add flatten decay tree + particle matching algorithms + ISBASICPARTICLE functor

• Adds the functionality to flatten a decay tree, similar to the "FilterInTrees" functionality without cut.
• Adds algorithm that allows to build a matching relation table based on LHCbIDs
• Adds ISBASICPARTICLE predicate functor to allow you to filter the Flattened Decay Tree

Qmtest and use example is in DaVinci: DaVinci!890 (merged)

(no it's not using FilterDesktop)
