/**
* Dialog widget allows an easy configuration to control javascript dialogs and also generate rich styled bootstrap
* modal dialogs using [bootstrap3-dialog](https://github.com/nakupanda/bootstrap3-dialog) plugin. The widget provides
* its own advanced javascript library `KrajeeDialog` that acts a polyfill for the native javascript alert, confirm, and
* prompt dialog boxes.
*
* **Example 1: ** Usage for a default dialog.
*
* ```php
* echo Dialog::widget([
* 'libName' => 'krajeeDialog',
* 'options => [], // default options
* ]);
*```
*
* **Example 2: ** Usage for a customized dialog.
*
* ```php
* echo Dialog::widget([
* 'libName' => 'krajeeDialogCust',
* 'options => ['draggable' => true, 'closable' => true], // custom options
* ]);
* ```
*
* Then you can use your own javascript as shown below to render your alert, confirm, and prompt boxes:
*
* ```js
* // use krajeeDialog object instance
* $('#btn-1').on('click', function() {
* krajeeDialog.alert('An alert');
* // or show a confirm
* krajeeDialog.confirm('Are you sure', function(out){
* if(out) {
* alert('Yes'); // or do something on confirmation
* }
* });
*
* });
*
* // use krajeeDialogCust object instance
* $('#btn-2').on('click', function() {
* krajeeDialogCust.alert('An alert');
* // or show a prompt
* krajeeDialogCust.prompt({label:'Provide reason', placeholder:'Upto 30 characters...'}, function(out){
* if (out) {
* alert('Yes'); // or do something based on the value of out
* }
* });
*
* });
* ```
