Returns dofmanager dof mask for node.

This mask defines the dofs which are used by element in node. Mask influences the code number ordering for particular node.

If element requests dofs using node mask which are not in node then error is generated. This masking allows node to be shared by different elements with different dofs in same node. Elements local code numbers are extracted from node using this mask. Must be defined by particular element.
