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.

Not Collective
Input Parameters
dm -the discretization manager object
Output Parameter
dof -the blocked global degree-of-freedom index array in the discrete representation (Vec, Mat) that is vertex-based based on local numbering
