\class RooAbsMCStudyModule
\ingroup Roofitcore
 
Base class for add-on modules to RooMCStudy that
can perform additional calculations on each generate+fit cycle managed
by RooMCStudy.
 
This class can insert code to be executed before each generation step,
between the generation and fitting step and after the fitting step.
Any summary output variables declared in the RooDataSet exported through
summaryData() is merged with the 'master' summary dataset in RooMCStudy.
 
Look at RooDLLSignificanceMCSModule for an example of an implementation.
