Hello again!

Why is it not possible any longer to get the Vector associated with a 
Function? E.g:

#include <dolfin.h>
using namespace dolfin;

int main()
{
  Function u;
  Vector& v = u.vector();
}

error: invalid initialization of reference of type ‘dolfin::Vector&’ 
from expression of type ‘dolfin::GenericVector’

I hope this functionality hasn't been removed.
