working on exposing barrier api
my rest api actually receiving requests
actually waiting until barrier comes to return
separate queues for each switch
put timeout back to 1 second
remove print
fix weird serialization crash
comment out barrier message output
include stax2 jar so response serialization doesn't break
Dockerfile
Added separate, standard config file for pronghorn floodlight.
Changed main class so that can make static call into it to produce a controller.
Sanitized spacing in pronghorn modules.
Goal is to move away from REST interface and instead have pronghorn make flow table changes directly through function call.  Thererfore, expanding pronghorn module's interface.
Ensuring that non-rest interface listens for error messages.
Pushing errors to preceding commands through barrier callback.
StaticFlowEntry pusher now exports facility for parsing actions into flow mods.
Does two things:

  1) PronghornModule will now push IOExceptions back to caller
  2) Starts trying to translate PronghornFlowTableEntry objects into
     OpenFlowMessages.
Added further fields for flow table entries.
Exported method for initializing flowmod methods.
