// This routine computes the 'best fit' plane equation to
// a set of input data points with an optional per vertex
// weighting component.
//
// The implementation for this was lifted directly from
// David Eberly's Magic Software implementation.
 
// computes the best fit plane to a collection of data points.
// returns the plane equation as A,B,C,D format. (Ax+By+Cz+D)
