Detailed Description

Example class that can be used to analyze pat::Muons both within FWLite and within the full framework.

This is an example for keeping classes that can be used both within FWLite and within the full framework. The class is derived from the BasicAnalyzer base class, which is an interface for the two wrapper classes EDAnalyzerWrapper and FWLiteAnalyzerWrapper. You can fin more information on this on WorkBookFWLiteExamples::ExampleFive.
