This cylindrical multi-grid operator itself is not calculating any real operator, instead it is hosting two separate "child" operators of type "Operator_Cylinder".
This operator class (or the corresponding engine) will perform the interpolation and connection between these two child-operator/engines.
One of the child operators itself may be another multi-grid operator to allow for a cascaded multi-grid approach.
