For some <A HREF="../DM/DM.html#DM">DM</A> implementations this is a shallow clone, the result of which may share (referent counted) information with its parent. For example,
<A HREF="../DM/DMClone.html#DMClone">DMClone</A>() applied to a <A HREF="../DMPLEX/DMPLEX.html#DMPLEX">DMPLEX</A> object will result in a new <A HREF="../DMPLEX/DMPLEX.html#DMPLEX">DMPLEX</A> that shares the topology with the original <A HREF="../DMPLEX/DMPLEX.html#DMPLEX">DMPLEX</A>. It does not
share the <A HREF="../PetscSection/PetscSection.html#PetscSection">PetscSection</A> of the original <A HREF="../DM/DM.html#DM">DM</A>.
<P>
The clone is considered set up iff the original is.
