<li><p>The idea of hybrid and ghost cells has been removed from Plex in
favor of cell type</p></li>
<li><p>Plex can now classify points by cell type, stored in a DMLabel.
This is useful for operations that require more than topological
data, such as mesh interpolation, geometric calculations, and is
also used an index to avoid repeated topological queries</p></li>
<li><p>Add DMPlexSetCellType() and DMPlexCreateReferenceCellByType()</p></li>
