I can't make up my mind whether I want 'ctype' or 'field_type'

ADOL-C doesn't play nice with OpenMP.  Hence we have to disable
the latter for the time being.

When using the classes with ADOL-C, T becomes an 'adouble',
which is a non-trivial type.  However, the convexityField
is constexpr (and with a reason -- otherwise we could write
the initialization together with the declaration), and
constexpr and non-trivial types don't work together.

And set the inner loop solver verbosity to QUIET

This number is nowadays infered from the number of transfer operators.

[[Imported from SVN: r9432]]

Since ADOL-C is not multi-threaded we will not be using OpenMP
in the foreseeable future.  And on a single-threaded code the
OpenMP timer and the Dune timer return the same values anyway.

Offer setInitialIterate instead

Because ADOL-C doesn't like calls to sqrt(0), obviously.
The use of sqrt(x) for small x can be avoided completely
using modified series expansions, because the overall
function exp is differentiable even at x=0.

Makes for a more precise Hessian matrix when using automatic differentiation.

Because it may contain a projection onto the manifold, which
is part of the energy evaluation if we view the energy as
being defined on all of R^n (as ADOL-C does).

Not actually working yet, though.

The only exception is the material parameters.  ADOL-C (for which
we are doing this), doesn't need to have them in a special type.

Saves us one call to sqrt().

This is needed to use the ADOL-C automatic differentiation library.
