Yes, I think we can remove it now. There is currently a working
compressible solver in dolfin-fsi, but since we are not clear over where
the different solvers in dolfin-fsi should go, I think we can remove the
current euler one.

If we want an euler solver demo in dolfin (or in a dolfin-modules project,
or similar) later on, we can readd a clean version of this solver.
