/*PubNub sample JSON-parsing client with WiFi support
 
  This combines two sketches: the PubNubJson example of PubNub library
  and the WifiWebClientRepeating example of the WiFi library.
 
  This sample client will properly parse JSON-encoded PubNub subscription
  replies using the aJson library. It will send a simple message, then
  properly parsing and inspecting a subscription message received back.
 
  This is achieved by integration with the aJson library. You will need
  a version featuring Wiring Stream integration, that can be found
  at http://github.com/pasky/aJson as of 2013-05-30.
 
  Please refer to the PubNubJson example description for some important
  notes, especially regarding memory saving on Arduino Uno/Duemilanove.
  You can also save some RAM by not using WiFi password protection.
