VirtualIntegrator abstract class. Interface defining the common methods for the numerical integrator classes of one and multi dimensions The derived class VirtualIntegratorOneDim defines the methods for one-dimensional integration. The derived class VirtualIntegratorMultiDim defines the method for multi-dimensional integration. The concrete classes for one dimension (e.g. GSLIntegrator) or multi-dimension (e.g. GSLMCIntegrator) can be created using the plug-in manager @ingroup Integration
