- long arrays
- ogs data arrays

Now changes are in the class, function, methods documentation and not in
the headers.
This unifies to the most common case.

This unifies the doxygen headers. If the (doxygen) header is not
starting with \file, the following documentation is attributed to a
different entity resulting is multiple copyright blocks and the like in
the doxygen's html files.

-now in header

- getDimensions() now called getNumberOfVoxelPerDimension()
- now input is ranges instead of min max
- and included restrictions to function (only positive cellsize)
- if ranges = 0 return 1 voxel per dimension
- removed constexpr of str cell_id_name
- clang-format

- now pnt is directly assigned without assigning i,j,k
and write them to a pnt

- tidied up includes
- moved cell_id_name to namespace
- docu cell_id_name
- secured to dereference property with "cell_id_name"

meshgenerators moved to meshtoolslib

-from MeshLib::PropertyVector<int> const& to auto

Allowing to make the functions from Vtu2Grid visible
for accessing them in the DataExplorer.

in the files in MeshToolsLib.
