it no longer inherits from CBindings. move steps abstract method into Remote class. This is a much more meaningful abstraction - because it is the principle behaviour that distinguishes each kind of Remote. add wrapper methods to CBindings. This provides a cleaner api for the Remote class. import abc as namespace throughout the package.
