These functions would typically be empty place holders in a template downloaded from this project, these functions are the functions called by the case statement in the Step Processor from the [Core Functions] so the function definitions should not be changed.
You would typically edit the contents these functions and call the relevant [Application Specific Functions] or [Utility Functions] for the particular step.
In some cases you may reuse the same [Application Specific Functions] for several step types e.g. in many applications you might use the same function for a text field and a date field, whilst the data entered is different the entry method might be the same.
