+/**
+ * TJuiControlOptions interface
+ *
+ * TJuiControlOptions is an helper class that can collect a list of options
+ * for a control. The control must implement {@link IJuiOptions}.
+ * The options are validated againg an array of valid options provided by the control itself.
+ * Since component properties are case insensitive, the array of valid options is used
+ * to ensure the option name has the correct case.
+ * The options array can then get retrieved using {@link toArray} and applied to the jQuery-ui widget.
+ * In addition to the options, this class will render the needed javascript to raise a callback
+ * for any event for which an handler is defined in the control.
