/**
* StopwatchPageModel class
*
* This is the data model class that is bound to the stopwatch.yml gui page that is defined in resources/yamls/stopwatch.yml
* All public methods of this class are available to be called from the stopwatch.yml config file
* Reference resources/yamls/stopwatch.yml to see how the GUIComponents used in this class were configured
*
* Methods can be called from the config file by using syntax: $model.myFunctionName();
* Example of this usage can be found in stopwatch.yml
*
* If the method returns a value, then that value will be replaced in the string in the config file
* This allows you to display dynamic data in your gui pages
