Add 2d projection demo and tests

Ted Stokes requested to merge TedStokes/nektar:feature/project-demo-2d into master

Issue/feature addressed

Previously no test for 2d h-type convergence.

Proposed solution

Add a demo and test of h-type convergence of a 2d continuous Galerkin projection.


Following MR !1738 (merged), the 1D Demos/MultiRegions/Project.cpp has been renamed to Project1D.cpp, and Project2D.cpp has been added, which can use either triangle or quadrilateral elements.


Triangle and quadrilateral tests added.
