Merge Developments in MCTC to master

Defined a new function which checks for hadron/tau/BSM/Geant/uncategorised origin and returns the output as a bitset converted to unsigned int. This unsigned int is decorated into a new branch called "Classification". This is part of a PMG effort to address deficiencies in the original MCTruthClassifier.

Classification scheme:

The following boolean flags are used:

• isStable: Whether the particle is stable (i.e. status 1) or not [1/0]
• isGeant: the particle originates in a nuclear interaction or not [1/0].
• isBSM: the particle itself is a BSM particle or not [1/0].
• uncat: HEPMC production vertex not found / found [1/0].
• fromBSM: there is a BSM particle in the ancestor chain or not [1/0]. Usual caveats apply.
• fromhad: there is a hadron in the ancestor chain or not [1/0].
• fromTau: there is a tau lepton in the ancestor chain or not [1/0].
• isHadTau: there is a tau lepton with a hadronic mother in the ancestor chain or not [1/0].

The flowchart below explains the logic flow:

Output

Runs only on truth particles. Creates 1 branch as mentioned above. "classify" function runs in parallel with the original MCTC functions.
