Public bug reported:

Local mesh refinement with options "bisection" or "iterative_bisection"
are broken. Crash with the error

dolfin/mesh/MeshTopology.h:50: dolfin::uint
dolfin::MeshTopology::size(dolfin::uint) const: Assertion `num_entities'
failed.

Only "recursive_bisection" is currently working.

The above algorithms should either be fixed or removed. Since
"recursive_bisection" (Rivara) is supposedly the best/fastest option, we
might as well remove the other two?
