Detailed Description

PatAnalyzerKit is a generic ED analyzer with predefined physics histograms.

This is an ED analyzer which creates and fills a bunch of histograms of various physics quantities. However, in order to make this also work in FWLite, most of the actual work is performed by another object called PhysicsHistograms, to which this ED analyzer delegates most of the work, except the interactions with EDM and Framework, like:

• obtaining parameters from edm::ParameterSet. PhysicsHistograms receives commands with lists of sub-components to manipulate (usually only enable or disable).

• fetching collections from the event (the iteration over collections is done by PhysicsHistograms).

• putting single numbers back to the event -- this is how flat ntuples are made. (PhysicsHistograms provides several lists of PhysVarHisto* pointers: 1. all PhysVarHistos 2. those that need to be histogrammed 3. those that need to be ntupled 4. those that need to be filled in each events (i.e. "active" ones, which is a union of (2) and (3), and a subset of (1).
