DMMoabGetVertexDofsBlocked

 Gets the global degree-of-freedom for the first field (component) defined on an array of locally owned MOAB mesh vertices. It's utility is when performing Finite-Difference type calculations where vertex traversal is faster than element-wise assembly that is typically done in FEM calculations.
