getSettings() {
        return this.settings;
    }
Return the options object containing all the current autoNumeric settings in effect.
You can then directly access each option by using its name : `anElement.getSettings().optionNameAutoCompleted`.

@example
anElement.getSettings()
anElement.getSettings().decimalCharacter // Return the decimalCharacter setting as a string - any valid option name can be used

@returns {object}
