                     selections can be defined here. This validates the option and also enables
                     a combobox / radio option in the GUI.
          gui_radio: [optional] If <choices> are defined, this indicates that the GUI should use
                     radio buttons rather than a combobox to display this option.
          min_max:   [partial] For <class 'int'> and <class 'float'> datatypes this is required
                     otherwise it is ignored. Should be a tuple of min and max accepted values.
                     This is used for controlling the GUI slider range. Values are not enforced.
          rounding:  [partial] For <class 'int'> and <class 'float'> datatypes this is
                     required otherwise it is ignored. Used for the GUI slider. For floats, this
                     is the number of decimal places to display. For ints this is the step size.
