update API getSwitch()

[shivarammysore]

In Class org.flowforwarding.warp.jcontroller.Controller.ControllerRef there are 2 methods - getSwitches() and getSwitch(dpid). Normal API design would be:

List<SwitchState.SwitchRef> getSwitch()

and

SwitchState.SwitchRef getSwitch(String dpid)

Thanks for the note, this is really a bad design. We're already working on Controller API, it will be completely re-designed soon.
