Renumber colors to start at zero and add check for contiguous coloring.
Something fails (segfault in coloring demo), will fix later.
I think that I've fixed the seg fault. It was related to code like
const MeshFunction<dolfin::uint>& colors_vertex = mesh.color("vertex");
const MeshFunction<dolfin::uint>& colors_edge = mesh.color("edge");
The function Mesh::color deletes the old data when asking for a new
colouring, which leave colors_vertex dangling. Could we re-use data, so
that the reference to colors_vertex remains valid? Or could we store
different colourings (vertex, edge, facet)?
