A proxy module is a module with a known structure, but
accessed over a SECoP connection.
For the configuration, a Frappy module class has to be given.
The proxy class is created from this, but does not inherit from it.
However, the class of the returned object will be subclass of the
SECoP base classes (Readable, Drivable etc.).
A possible extension might be, that instead of the Frappy class,
the JSON module description can be given, as a separate file
or directly in the config file.
Or we might offer a tool to convert the JSON description to
a python class.
