The permutation is already in. Using the numbers requires to have the
correct global state whenever the key is evaluated, which we cannot
guarantee.

Merge branch 'bugfix/fix-vectorization-with-modified-qp-tuple' into 'master'

ref:extensions/dune-codegen The unstructured stuff changed the implementation
of the parallel key to depend on the quadrature tuple. This means that we need
to make sure that the state of the quadrature tuple is correctly all the time!

Merge branch 'feature/geometry-mixins' into 'master'

ref:extensions/dune-codegen This MR switches the way we allow configurable
handling of geometry, quadrature and basis evaluation. So far, we had an
interface class - one for PDELab, sum factorization and block structuring.
This had the disadvantage of being quite monolithic. Also, different
geometries (equidistant, axiparallel, multilinear etc.) were handled through a
backend mechanism that performed fine for simple examples, but could get quite
messy for complex ones.

The new way introduced here is mixin classes. Mixins for the above topics can
be defined anywhere in the code (even in user code, if a poweruser wants to
implement his own geometries!!!) and are registered through a decorator. The
visitor is then constructed by choosing a set of mixins and combining them
into a class. This is currently done through ini options.

TODO:

-   \[x\] Allow generators to be used as class methods
-   \[x\] Implement basic mixin infrastructure
-   \[x\] Construct a visitor by combining mixins
-   \[x\] Port existing geometry implementations
    -   \[x\] Generic PDELab
    -   \[x\] Axiparallel
    -   \[x\] Equidistant
    -   \[x\] Blockstructured
    -   \[x\] Sumfact: Multilinear
-   \[x\] Remove *Interface* Concept in favor of mixins
-   \[x\] Final cleanup

This fixes [#128].
