Re: Vector type casting

 

Would it be better to put the functions for casting in GenericVector (or perhaps even better in GenericTensor)?

There's something fishy with the system I'm on now.

If you can pull from
  hg pull ssh://yourname@xxxxxxxxxx//home/martinal/hg/dolfin
run the tests and push if it works, that would be great.

I have to run now, so I'll have to finish this later if there's anything wrong.
