Well, something is better than nothing. Now it looks like:

class DirichletBC(cpp.DirichletBC):

    def __init__(self, *args):
        "Create Dirichlet boundary condition."

Which is really nothing. A user need to look in a demo to understand how to 
use it. Especially with the magical AutoSubDomain feature...
