Add test for Dirichlet boundary condition, tidy-up DirBndCond and NeuBndCond operators implementation, and RobBndCond operator
- Tidy-up DirBndCond operator implementation
- Tidy-up NeuBndCond operator implementation
- Add new RobBndCond operator for Robin boundary conditions
- Create a
tests/init_dirchletfields.hpp
subclass to reduce code duplication. - Consistently add test for quad, tri, and hex
- Use Nektar++ for reference solution.
