Handle reconstruction info consistently

[tdealtry]

The current ReconInfo model doesn't work for add energy. Need to come up with something more generic, that can handle chains from trigger to final result(s) of unspecified length e.g.

• Trigger -> BONSAI vertex -> Seed to Energetic BONSAI energy
• Trigger -> TestVertices vertex -> Seed to BONSAI vertex -> Seed to other vertex finder -> Seed to Energetic BONSAI energy
