A method to obtain existing object or data role

[wrobell]

Having name of a role, it would be great to be able to obtain an existing role, be it object or data property.

For example (in pseudocode)

# in context 1 of a  program
role = kernel.object_role('A')  # creates object role A
...
# in context 2 of a program
role = kernel.role('A')  # retrieves existing role A; raise an error if it does not exist
role.is_object() == true  # check if role is an object role

Or is that already possible with current API?
