/**
* ## Visibility Switcher Extension
*
* Use this extension in a parent element to easily define the visibility of child elements during the
* mouse hover of their containers. When the "mouseleave" event is triggered the children will be hidden.
*
* ### Options
*
* **Rows | data-visibility_switcher-rows | String | Required**
*
* Provide a jQuery selector string which points to the elements that have the "hover" event.
*
* **Selections | data-visibility_switcher-selections | String | Required**
*
* Provide a jQuery selector string which points to the elements to be displayed upon the "hover" event.
*
* ### Example
*
* In the following example the .row-action elements will be visible whenever the user hovers above of the
* `<tr>` element. The initial state of the elements must be hidden (thus the 'hidden' class).
*
* ```html
* <table data-gx-extension="visibility_switcher"
* data-visibility_switcher-rows="tr.row"
* data-visibility_switcher-selections="i.row-action">
* <tr class="row">
* <td>#1</td>
* <td>John Doe</td>
* <td>
* <i class="fa fa-pencil row-action edit hidden"></i>
* <i class="fa fa-trash row-action delete hidden"></i>
* </td>
* </tr>
* </table>
* ```
*
* *Whenever the user hovers at the table rows the .row-action elements will be visible and whenever the
* mouse leaves the rows they will be hidden.*
