			``GooseFEM::Mesh::dofs``
			========================

			Get a sequential list of DOF-numbers for each vector-component of each node.

			.. code-block:: cpp

			MatS GooseFEM::Mesh::dofs ( size_t nnode , size_t ndim )

			For example for 3 nodes in 2 dimensions the output is

			.. math::

			\begin{bmatrix}
			0 & 1 \\
			2 & 3 \\
			4 & 5
			\end{bmatrix}

			``GooseFEM::Mesh::renumber``
			============================

			* Renumber indices to lowest possible indices (returns a copy, input not modified).

			.. code-block:: cpp

			MatS GooseFEM::Mesh::renumber ( const MatS &in )

			For example:

			.. math::

			\begin{bmatrix}
			0 & 1 \\
			0 & 1 \\
			5 & 4
			\end{bmatrix}

			is renumbered to

			.. math::

			\begin{bmatrix}
			0 & 1 \\
			0 & 1 \\
			3 & 2
			\end{bmatrix}

			* Reorder indices such that some items are at the beginning or the end (returns a copy, input not modified).

			.. code-block:: cpp

			MatS GooseFEM::Mesh::renumber ( const MatS &in , const VecS &idx, std::string location="end" );

			For example:

			.. math::

			\mathrm{in} =
			\begin{bmatrix}
			0 & 1 \\
			0 & 1 \\
			3 & 2 \\
			4 & 5
			\end{bmatrix}

			with

			.. math::

			\mathrm{idx} =
			\begin{bmatrix}
			6 & 4
			\end{bmatrix}

			Implies that ``in`` is renumbered such that the 6th item becomes the one-before-last item (:math:`5 \rightarrow 4`), and the 4th item become the last (:math:`3 \rightarrow 5`). The remaining items are renumbered to the lowest index while keeping the same order. The result:

			.. math::

			\begin{bmatrix}
			0 & 1 \\
			0 & 1 \\
			5 & 2 \\
			4 & 3
			\end{bmatrix}
