+ * Specialization of the general DoFAccessor class template for the
+ * case of zero-dimensional objects (a vertex) that are the face of a
+ * one-dimensional cell in spacedim space dimensions. Since vertices
+ * function differently than general faces, this class does a few
+ * things differently than the general template, but the interface
+ * should look the same.
