ref:staging/dune-uggrid Merge branch 'fix/issue51-loadbalancer' into 'master'

ref:staging/dune-uggrid ebf74cbf replaces
three sort functions by a template. However, the template arguments were never
used in the function, so we only sorted in one coordinate direction. This
commit fixes this by replacing the hard-coded indices with the template
argument values.

Thanks to Leopold Stadler for finding the offending commit.

-   Should be backported to the release/2.7 branch.

Fixes [[#51]]

Merge branch 'remove-obsolete-amglevel-access' into 'master'

ref:staging/dune-uggrid The UG3 multigrid data structure used to have an array
'amggrids' with grid levels for AMG. That array is long gone, but it was still
overwritten with nullptrs in the multigrid setup code. A serious memory bug,
and I am amazed that nobody ever observed any effects.

ref:staging/dune-uggrid The hack to have every sub-directory in the include
path does no longer work for me. Time to get it fixed by making the include
paths relative to dune-uggrid root directory.

-   include paths relative to dune-uggrid root directory
-   move header files below dune/uggrid/.
-   drop folder ug/ and compatibility with UG 3.13.

Closes #13

The old helper variable parallel was
removed by accident.
UG_PARALLEL is set to "True", no longer to "yes".

Similar to other Dune modules

The files were for compatibility only. They are
superseded by files created for any Dune module.

Delete parallel/.

Couple of links, only for backwards compatiblity with ug 3.13

Remove unused subfolder dom/gen/ and its content.

But it remains meaningless
