PubNub Spark Core Library
This library allows your Spark apps to communicate with the PubNub cloud message passing system - your apps can receive and send messages.
This is currently just a snapshot of a work in progress. It does not compile yet, but the PubNub.* code and the PubNubDemo example are transitioning in that direction.
The Spark Core development environment is, as of January 2014, unsuitable for usage of complex third-party libraries. We are now holding back our port to give the awesome Spark.io guys a bit more time to enhance the versatility of their environment.
