  Basic ESP8266 MQTT example

  This sketch demonstrates the capabilities of the pubsub library in combination
  with the ESP8266 board/library.

  It connects to an MQTT server then:
  - publishes "hello world" to the topic "outTopic" every two seconds
  - subscribes to the topic "inTopic", printing out any messages
    it receives. NB - it assumes the received payloads are strings not binary
