class RooNumIntFactory: public TObject

 Constructor. Register all known integrators by calling
 their static registration functions

 Destructor

 Copy constructor

 Static method returning reference to singleton instance of factory

 Cleanup routine called by atexit() handler installed by RooSentinel

 Method accepting registration of a prototype numeric integrator along with a RooArgSet of its
 default configuration options and an optional list of names of other numeric integrators
 on which this integrator depends. Returns true if integrator was previously registered

 Return prototype integrator with given (class) name

 Get list of class names of integrators needed by integrator named 'name'

 Construct a numeric integrator instance that operates on function 'func' and is configured
 with 'config'. If ndimPreset is greater than zero that number is taken as the dimensionality
 of the integration, otherwise it is queried from 'func'. This function iterators over list
 of available prototype integrators and returns an clone attached to the given function of
 the first class that matches the specifications of the requested integration considering
 the number of dimensions, the nature of the limits (open ended vs closed) and the user
 preference stated in 'config'
