b tagging

Implementation

We do not b-tag our fatjets. Instead, we match each fatjet to an AK4 jet in the miniAOD collection and assign our fatjet the AK4 jet's b-tag discriminator.

We use the loose CSV working point for moriond17, defined on the BtagRecommendation80XReReco Twiki page to be 0.5426.
