/**
* Module for adding loader animations to dom nodes.
*
* The default loader animation can be added or appended/prepended as follows
*
* var loader = require('ui.loader');
*
* // Overwrite current html content with loader animation
* loader.set(myNode);
*
* // Remove loader animation
* loader.reset(myNode);
*
* The loader module also adds an click handler to all buttons and links with a
* data-ui-loader attribute set.
*
* If a data-ui-loader button is used within a yii ActiveForm we automaticly reset all loader buttons
* in case of form validation errors.
*
*
* @param {type} param1
* @param {type} param2
