The examples/2019-generate-tip-demo.py helper script can be used to
generate a ring topology where each "ROADM node" consists of three
separate ROADMs and two pairs of booster+preamp EDFAs. This will be used
at the TIP Summit to show integration between ONOS and GNPy.
The topology *and the equipment library) more or less corresponds to the
CzechLight OLS that is planned for the exhibition.
