Detailed Description

This concrete class implements MApp the polls a model point for a temperature value and periodically writes the value to the trace output.

The MApp also collects some metrics and has the option to display temperature in degrees Fahrenheit or Celsius.

NOTE: Multiple of instance of the class can be created - as long as each instance has a unique 'name'.

The class is intended to be example/template for an MApp - not that it does anything particular noteworthy.
