- add MPI_Comm wrapper
- add conversion from mpi4py.MPI.Comm to MPI_Comm wrapper
- allow to construct dune.common.Communication from mpi4py.MPI.Comm

to use during unpickling to compile modules in dune-py if not available

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

The function dune.common.registerExternalModule(module) has
to be actively called in the downstream module to register
an external package. This triggers the reconfiguration of dune-py
in case dune-py has already been created.

- moved some parts relating to the venv out of PythonCommonMacros to Virtualenv
- removed PythonMacros file
- use an external active env instead of generating a new internal one.
  Also added some checks to avoid a user mixing up different builds within the same env
- finally made some changes on how and when the dune-py module is regenerated

some minor fixes

[testing] ci with index-url set

remove extra-index-url from pip install

add a stopgap solution unti ci repo up and running again

we need pip>=21 so that 'make', 'make install_python', 'make' does not
mess up the packages in an external env (with older versions of pip
the last 'make' wouldn't correctly remove the non editable install).

[bugfix]

remove some debug output

to automate generation of metadata for setup.py for other modules

[bug fix] previous commit

move files around a bit to be able to use the metaData extraction
from dunepackaging.py

use more of the cmake variables in python/setup.py.in

fix an issue in dunepackaging.py for modules without a python package

- remove CMakeCache.txt file in dune-py
- check that pyproject.toml file contains all dune module dependencies
  mentioned in dune.module to check consistency

[bug fix] previous commit

add dune modules from pyproject.toml to install_requires in setup.py

[bug fix] previous commit

added files generated when calling python setup.py sdist to git ignore list

Update bin/dunepackaging.py.

Add path to dunepackaging if dune-common.

Append version number devDATE to -git versions and add suggestions if they have a pypi package.

Build shared libraries with .so suffix on Mac.

Install pybind11 modules.

Generate dependencies of dune-py on-demand.

fixed a few issues with generating dune-py on a linux machine

add numpy, mpi4py to required packages

remove some python 2 related code and fixed up some other issues
pointed out by Timo
deprecated old compatibility file - move Python 3 code to dune.common.utility

move bin files and cmake modules from dune-python
add sphinx support from dune-python

This makes it possible to import "statefull" C++ objects to Python.
At the moment only the constructor is available on the Python side
so the object can only be used as argument for another C++ function/method.
Exporting methods will be made available as well in a future version.

The builder exceptions should be shared between different implementations of the
builder interface. This patch migrates them to a separate module
`dune.generator.exceptions`. For convenience they are also imported into
`dune.generator` itself.

This allows them to be loaded without loading the corresponding Python
mdoule, avoiding circular dependencies.

This patch exports all enum-types defined in dune-grid (or added by
dune-python and associated to dune-grid) to the Python namespace
dune.grid.

Due to the changes in dune.grid, the PartitionIteratorType is no longer
required and, hence, is removed. It has been superseeded by the exported
partition objects.

Building Python modules through Pybind11 is a recurring task in our
Python bindings. To reduce maintainance in the build system, we introduce
a CMake function "dune_add_pybind11_module", which is semantically inspired
by the "dune_add_test" function.

This module simply imports everything from cPickle or pickle, depending on
the Python version.

included for this function

of a HAVE_FOO in config.h can be tested for. A possible usage is shown in
spgrid/_grid.py
Other checks can be added in a similar manner
