lowest order C^1 space
Implement lowest order C^1 space. Needs order=3
and testSpaces = [[0, 0], [-1, -1], [-1]]
.
In addition to some other minor changes this adds a laplace
constraint to the value projection because
otherwise we have fewer dofs than the dimension of P^3: int laplace Pi^0 v = int_boundary v.n
Builds on div-free space and requires dune-fem feature/improvePythonQuadPoints branch.
