Fixed typo.

Refactored Triangulation to use TriaAccessor::center.
Bugfix: Only include ./bundled/setup_bundled.cmake

Remove a stray globbing expression that is not necessary any more and that
indeed leads to a subtle issue when configuring in-source with
  $ cmake .

In this case ./bundled/cmake_install.cmake was accidentally picked up
leading to a file permission error if CMAKE_INSTALL_PREFIX was left at the
default /usr/local
use the fe index also in the case where triangulation was prepared for pure refinement

and add test that would fail without the patch and works fine now

ADd documentation to the hp::DoFHandler class.
Updated documentation for step-20 Introduction section and a typo in the documentation for iterative_inverse.h. Detailed: In the introduction of the step-20 tutorial, Sec. Solving using the Schur complement, the IterativeInverse class is introduced and then in the following code section not used. Now the InverseMatrix is changed to IterativeInverse< .. > to match with the code of the tutorial, as used below.
Merge pull request #149 from koecher/master

Updated documentation
Remove references to MGDoFHandler.

MGDoFHandler has been deprecated for a while already. Remove all
references to it from this documentation module.
Remove another reference to MGDoFHandler.
Merge pull request #150 from bangerth/doc-update-2

Remove a few references to MGDoFHandler as that class is no longer relevant.
Merge pull request #146 from bangerth/rework-mpi-initialization

Add a version of MPI_InitFinalize that adaptively determines the number of threads
Updated Documentation. Again, in the Introduction section of the step-20 tutorial a class InverseMatrix appears. Now its changed to use IterativeInverse<..> in all places to match with the code.
