Defining custom topologies, switch types, controllers, and hosts is now much easier. Plus, all Ripcord-specific stuff has been moved out.
This directory should hold configuration files for custom mininets. See custom_example.py, which loads the default minimal topology.

Each custom file must define a Mininet object for an 'mn' variable. To start up a mininet with this custom topology, do: sudo mn --custom custom_example.py
