I added this.

I tried this is demo/pde/sym-dirichlet-bc/python/demo.py, but I get

Traceback (most recent call last):
  File "demo.py", line 55, in <module>
    bc = cpp_DirichletBC(u0, mesh, boundary)
NameError: name 'cpp_DirichletBC' is not defined


As you say, this is a problem with this

Is there a way to 'up cast' Python objects. For example, DirichletBC is 
derived from cpp_DirichletBC, so can I get a cast a DirichletBC object 
to a cpp_DirichletBC object?
