there will be less dependence on the grid subdirectory.

Also, this file contains a new class NewGeometryType is should eventually
replace the old enum.  It is roughly as planned in FlySpray task 66.

The name NewGeometryType is obviously not satisfying.  I would have
prefered EntityType, ElementType, or GeometryType, but all of them
are taken already.

contains only some boundary segments with parametrizations, only
those have to be given explicitly.  The remaining ones are inserted
automatically as straight-line segments.

two files. So, sequential applications do not try to include MPI even if HAVE_MPI is true

Only comm() should be used

- fixed Task #67, P1 functions and operators should work level and leafwise now also in parallel

1) Generation of sparse matrix
2) Assembling of global stiffness matrix from local stiffness matrices
3) Interface for providing a local stiffness matrix and boundary conditions

All this is only for P1, but it works with hanging nodes, in parallel (with
algebraic extension of nonoverlapping grids) and for systems.
(Systems are yet untested).

that seperates it in a local (elemenwise) part and a global part

matrix row.

Compiles again and works for the sequential case.
