Adding first implementation of the B2G DQM Modules


This is the long-awaited B2G DQM module, version 1.0. 

There are a few technical changes that had to happen for this : 

1. We had to move the top-tagging algorithms and dataformats from AnalysisDataFormats/TopObjects and TopQuarkAnalysis/TopPairBSM into RECO-accessible packages, DataFormats/JetReco, RecoJets/JetProducers and RecoJets/JetAlgorithms.

2. Currently only a few jet collections are being monitored, AK5, AK5CHS, CA8, CA8 pruned, and CA8 top tagged. more to follow. 

So I think we've now required 8 people to sign off on these changes. Sorry ;). 

Cheers,
