Using new GMSH interface in DOLFINx (dolfinx.io.gmshio) in all demos using GMSH
Added a section on custom Newton-solvers, see [chapter4/newton-solver].
Various minor DOLFINx API updates. dolfinx.mesh.compute_boundary_facets -> dolfinx.mesh.exterior_facet_indices with slightly different functionality. Use dolfinx.mesh.MeshTagsMetaClass.find instead of mt.indices[mt.values==value].
Various numpy updates, use np.full_like.
Change all notebooks to use jupytext to automatically sync .ipynb with .py files.
Add example of how to use DOLFINx in complex mode, see [chapter1/complex_mode].

All pyvista plotting has been rewritten to use ipygany and pythreejs as well as using a cleaner interface.
dolfinx.plot.create_vtk_topology has been renamed to dolfinx.plot.create_vtk_mesh and can now be directly used as input to pyvista.UnstructuredGrid.
dolfinx.fem.Function.compute_point_values has been deprecated. Interpolation into a CG-1 is now the way of getting vertex values.
API updates wrt. DOLFINx. Form->form, DirichletBC->dirichletbc.
Updates on error computations in Error control: Computing convergence rates.
Added tutorial on interpolation of ufl.Expression in Deflection of a membrane.
Added tutorial on how to apply constant-valued Dirichet conditions in Deflection of a membrane.
Various API changes relating to the import structure of DOLFINx

Major improvements in Form compiler parameters, using pandas and seaborn for visualization of speed-ups gained using form compiler parameters.
API change: dolfinx.cpp.la.scatter_forward(u.x) -> u.x.scatter_forward
Various plotting updates due to new version of pyvista.
Updating of the Hyperelasticity demo, now using DOLFINx wrappers to create the non-linear problem
Internal updates due to bumping of jupyter-book versions
Various typos and capitalizations fixed by @mscroggs in PR 35.
