OnlyDegenerate -- restrict to degenerate geometric vertex decompositions


Set to true to restrict the output of findOneStepGVD to return only the indeterminates for which their geometric vertex decomposition is degenerate. Default value false. Following the notation of oneStepGVD, a geometric vertex decomposition is degenerate if either $\sqrt{C_{y, I}} = \sqrt{N_{y, I}}$ or if $C_{y, I} = \langle 1 \rangle$, and is nondegenerate otherwise.
