The new implementation uses only local topology information to
distinguish base and "higher" order nodes.

The latter relies on local information of element types
and number of nodes, not the global numbering of nodes.

The connection information can be computed
on the fly required.

Rename setNodesConnectedByElements to
calculateNodesConnectedByElements and make it a free
function. This 'out sourcing' makes it possible to
compute the connection information only when it is
required.

This change makes it possible to use interface
function Element::getNode() in Element::addNeighbor
function.

This remove one dependencies on _nodes pointer C array.
If all dependencies are removed the memory for storing
the nodes can be in a std::array.

The getContent() method is used only on very few
places. Especially, it isn't used in the computation
of any THMC processes. So the content doesn't need
to be stored which saves memory. Furthermore, the time
time for reading / initializing a mesh is reduced.

In a hex mesh with 100x100x100 elements this saves
2.6% of storage and circa 25% time.

On Windows absolute path inside xdmf to hdf was incorrect. Fix to relative path because file must be transferable

This mv one dependency from _neighbors from the
base class Element to the class TemplateElement.
