UI for mgnorm

The mgnorm is constructed from a structure with fields:

                        system = {
                                type = "mgnorm";
                                // function for mean value evolution
                                g = {type="fnc"; ... }

                                // variance
                                R = [1, 0,
                                         0, 1];
                                // --OR --
                                dR = [1, 1];

                                // == OPTIONAL ==

                                // description of y variables
                                y = {type="rv"; names=["y", "u"];};
                                // description of u variable
                                u = {type="rv"; names=[];}
                        };
