As the communicator class needed for a module can be specified,
in the configuration we do not need to specifiy it explicitly.
A new configurator function IO() is introduced for this, defining
names and uri only.
- update also configuration reference and a tutorial example
- update get_class function to accept attributes of classes like
'frappy_demo.lakshore.TemperatureSensor.ioClass' and import from
modules other than frappy... like 'test.test_iocfg.Mod'.
- add ioClass to the example class for the temperature controller
