  See the new methods AssembleDiagonal in BilinearForm, AssembleDiagonalPA in
  BilinearFormIntegrator and the implementations in fem/bilininteg_*.cpp.
  -- Added initial support for partially assembled NonlinearForms.
  +- Added initial support for NonlinearForms to support the partial assembly mode.
  -- Added a nonlinear full and partial assembly enabled vector valued convection
  - integrator.
  +- Added a nonlinear vector valued convection integrator (Q u \cdot grad u, v)
  + where u_i and v_i are in H1. This form occurs e.g. in the Navier-Stokes
  + equations. The integrator supports the partial assembly mode for its
  + action. In full assembly mode we also provide the GetGradient method that
  + computes the linearized version of the integrator.
  - Added a new method, MixedBilinearForm::FormRectangularLinearSystem, that can
  be used to impose boundary conditions on the non-square off-diagonal blocks of
