Interface (abstract) class for multi numerical integration It must be implemented by the concrete Integrator classes like ROOT::Math::GSLMCIntegrator.
Plug-in's exist in ROOT to be able to instantiate the derived classes via the plug-in manager. Users should not use directly this class but the concrete classes ROOT::Math::IntegratorMultiDim.
