Tag sorter

Hi Seth,

TagSorter now up and running. Using Comissioning/config/tag_sorter.py to run.
The printed output is the given tag for each event with a valid diphoton. I realise that now the globelikeTreeMakerWithTagSorter probably needs to be turner on its head, so that we only store information directly from the Tags rather than from the diphotons... (at the current stage it isn't certain that the diphoton information from one part of the tree is necessarily from the same diphoton as selected by the tag). Anyway, just a thought for the future.
