Added a RaviartThomas element for tetrahedra
Added RT03LocalFiniteElement
a RaviartThomas
local finite element for simplices with dim=3
and k=0
.
Used the basis returned from RaviartThomasSimplexLocalFiniteElement()
(see dune/localfunctions/raviartthomas/raviartthomassimplex.hh
).
Added corresponding tests to dune/localfunctions/test/raviartthomaselementtest.cc
Passed all tests from dune-localfunctions
.
A merge request to integrate it into dune-functions
will follow.
