Nobody uses Amira, so the AmiraMesh format is obsolete.

This is much cleaner than handing over the Grid only, and then trying
to guess the basis using the preprocessor.  After all, the
RiemannianTrustRegionSolver calls the assembler, so it may know the
function space basis.

Kudos to Carsten Gräser for those new Python functions.

This is only a prototype, because the GFE solution function is replaced by
on where the interpolation is done in the embedding space.  That defeats the
purpose of measuring the GFE discretization error :-) but it is easier to
implement.  The real thing will follow shortly.

We can do it without the preprocessor.

I don't think I will need that again in the foreseeable future.
If ever it should be needed again the code can be taken from the
subversion archive.

Do not fall back to 'harmonicmaps.parset' by default.

... so much difficult code obsolete now... AD rocks...

This is much more flexible and *much* easier to use.

Along the way, this patch scraps several old hard-coded Dirichlet boundary
values.  I don't even remember what they were good for.  If they are needed
again they should also be reimplemented in Python.

Code doesn't compile due to some VirtualRefinement weirdness, though.
