FEniCS build scripts

Build PETSc, SLEPc, DOLFIN/FENICS, mshr within a Python virtualenv, using system dependencies for OpenMPI, BLAS, LAPACK, HDF5, etc. (credits: inspired by https://bitbucket.org/unilucompmech/fenics-gaia-cluster)

Dependencies on CentOS 8.1 (default)

For mshr:

Configure and run build_all.sh:
```
    ./build_all.sh |& tee build.log
```
Load the FEniCS environment (modules, environment variables, python venv) with:
```
  source $PREFIX/share/dolfin/dolfin.conf
```
where $PREFIX is as specified in build_all.sh.

Test the installation with the Poisson example:

    python3 test_poisson.py

and in parallel:

    mpirun -n 4 python3 test_poisson.py
