     * Important Note
     * ==============
     * If you initialize more than one then it will override previous settings and events.
     * To maintain previous events, pass the whole setting once again with changes within it.
     * Now it will override events
     *
     * Example of more than one initialization:
     * $(".numberTextBox").inputNumericTextBox();
     * var n = $(".numberTextBox").inputNumericTextBox({
     *     negativeAllow: false,
     *     decimalAllow: true
     * });
     * console.log(n);
