What is the purpose of the Private Method Listing?
The Private method listing allows for Ruby methods to be defined that can be used by the other command methods in the GSD device. You can place for example, a function to output a Log message, or a function to calculate a volume measurement based on percentage or an arbitrary value, etc.
