\class   genie::EventGeneratorI
 
\brief   Defines the EventGeneratorI interface.
 
         The concrete implementations of this interface are Event Record
         Visitors (subclasses of the EventRecordVisitorI pABC) that,
         additionally, declare a 'Validity Context'. \n
 
         The declared validity context is used for selecting the appropriate
         concrete EventGeneratorI to generate the interacion at hand using
         the 'chain-of-responsibility' design pattern.
