Updated floodlight submodule, and pointed it at a repo that I control.
Trying to avoid using REST interface to floodlight and instead
starting a module that I can instead execute direct function calls on.
Upated floodlight dependency to use /tmp to save its temporary files.
Adding a non-rest interface to floodlight.
Updated single_host to use non-rest interface to floodlight.  Still must update non-rest shim interface to actually process commands.
Updated floodlight external so that can receive switch added/removed notifications from non-rest interface.
Updated new floodlight interface to track switches' entering and leaving network.
Shim to floodlight through method calls should no longer be runnable:
it spawns a separate thread to floodlight in its constructor.
