/**
 This is a sample program to illustrate the use of the MQTT Client library
 on the mbed platform.  The Client class requires two classes which mediate
 access to system interfaces for networking and timing.  As long as these two
 classes provide the required public programming interfaces, it does not matter
 what facilities they use underneath. In this program, they use the mbed
 system libraries.
