See https://reuse.software/ for a description.

The routines traverse the container recursively and call a functor
at each scalar entry passing also the flat index.

This makes the naming consistent again.

The file colcompmatrix.hh contains the rudimentary implementation
of a sparse matrix with scalar entries and column-compressed storage.
As part of cleaning up the UMFPackSolver implementation this patch
moves the matrix class into a separate file.  What's left in
colcompmatrix.hh is the matrix setup code.

The plan is to turn the matrix into something ressembling a real
dune-istl matrix.  That should make the code easier to understand,
and maybe something will even need compressed-column matrix
for other things one day!

Based on the intial implementation by Oliver Sander (see !168)

A simple implementation for the SuiteSparse CHOLMOD solver for real valued
(double) linear systems.
Ignore dof's are supported.
The user has to take care of the correct size of
vectors in the "apply" method.

This file, while being called 'example', was actually a set of unit
tests.  The stuff it tested was all covered by the standard unit
tests.  Having these additional tests in a file with a misleading
name, and at a location outside of the standard test locations,
was confusing (for me, at least).  This patch simply removes
the file.

With the 'example.cc' file gone, the directory 'dune/istl/tutorial'
is empty.  Therefore this patch removes that directory, too.

Commit 8da92ce1 added allocator.hh but
forgot to add it to the installed headers in CMakeLists.txt.

This header is included by the installed headers superlu.hh and
supermatrix.hh.

There are some tests, which are hard to port in the paamg directory.
They want to explicitly test _without_ direct solver. Previously,
you simply did not add the flags for the direct solver packages.
add_dune_test relies on all flags, so we need a way to disable components
again. That will be implemented as part of dune_add_executable. For
now, we build the targets ourselves and hand them to dune_add_test.

initial commit of one class template for performing some iterative
eigenvalue algorithms based on power iteration and of one class
template for performing some eigenvalue algorithms provided by the
ARPACK++ library

It was moved to dune-common in Dune 2.3.

This commit contains
- a wrapper for the C library UMFPack
- tests for both CMake and autotools to find UMFPack on the system
- a unit test for UMFPack
- a new MatrixType ColCompMatrix which is a base class for a column
  compressed matrix. SuperLUMatrix now inherits from this base class.
  This way, no code is duplicated for the very similar interface in
  UMFPack.
- the SuperLU-specific part of OverlappingSchwarz code is abstracted
  to work with either SuperLU or UMFPack

The last commits caused compile errors for e.g. clang as I used
incomplete (only forward declared) types in template classes.
This patch moves the definition of InverseOperator and Preconditioners
from the headers solvers.hh and preconditioners into new separate
headers solver.hh and preconditioner.hh. This allows to include these
definitions in the previous headers without cause circular include directives.
