\description{
When there are 3 or more variables in the data, this function produces
             a matrix with ellipses drawn in the upper triangle.  The ellipse in cell
             \eqn{i,j} of the plot is drawn to be a contour of a standard bivariate
             normal with correlation \eqn{\rho_{ij}}.  One ellipse is drawn in each
             cell for each model in the \code{covfm} object.  When there are 2
             variables in the data, this function produces a scatter plot of the data
             with an overlaid 95\% confidence ellipse for each model in the
             \code{covfm} object.
