Detailed Description

Apply a json filter, and creates an RLTInfo TTree.
See PhysicsTools.HeppyCore.utils.RLTInfo for more information

example:

jsonFilter = cfg.Analyzer(
  "JSONAnalyzer",
  )

The path of the json file to be used is set as a component attribute.

The process function returns:
  - True if
     - the component is MC or
     - if the run/lumi pair is in the JSON file
     - if the json file was not set for this component
  - False if the component is MC or embed (for H->tau tau),
      and if the run/lumi pair is not in the JSON file.
