Recursively yield L{MethodicalMachine}s and their FQPNs within a
L{PythonModule} or a L{twisted.python.modules.PythonAttribute}
wrapper object.
Note that L{PythonModule}s may refer to packages, as well.
The discovery heuristic considers L{MethodicalMachine} instances
that are module-level attributes or class-level attributes
accessible from module scope. Machines inside nested classes will
be discovered, but those returned from functions or methods will not be.
@type within: L{PythonModule} or L{twisted.python.modules.PythonAttribute}
@param within: Where to start the search.
@return: a generator which yields FQPN, L{MethodicalMachine} pairs.
