/**
 * yii is the root module for all Yii JavaScript modules.
 * It implements a mechanism of organizing JavaScript code in modules through the function "yii.initModule()".
 *
 * Each module should be named as "x.y.z", where "x" stands for the root module (for the Yii core code, this is "yii").
 *
 * A module may be structured as follows:
 *
 * ```javascript
 * yii.sample = (function($) {
 *     var pub = {
 *         // whether this module is currently active. If false, init() will not be called for this module
 *         // it will also not be called for all its child modules. If this property is undefined, it means true.
 *         isActive: true,
 *         init: function() {
 *             // ... module initialization code go here ...
 *         },
 *
 *         // ... other public functions and properties go here ...
 *     };
 *
 *     // ... private functions and properties go here ...
 *
 *     return pub;
 * })(jQuery);
 * ```
 *
 * Using this structure, you can define public and private functions/properties for a module.
 * Private functions/properties are only visible within the module, while public functions/properties
 * may be accessed outside of the module. For example, you can access "yii.sample.isActive".
 *
 * You must call "yii.initModule()" once for the root module of all your modules.

         * Starting from version 2.0.3, the `data-params` attribute is also recognized when you specify
         * `data-method`. The value of `data-params` should be a JSON representation of the data (name-value pairs)
