Detailed Description

ISF interface class for TruthIncidents. Information regarding interactions that occur inside simulators are wrapped into dedicated TruthIncident implemenations. The ITruthIncident interface offers a layer of abstraction to the ISF framework, in order to build a MC truth record of the simulated event.
