-/**
- * @class Ext.LoadMask
- * A simple utility class for generically masking elements while loading data.  If the {@link #store}
- * config option is specified, the masking will be automatically synchronized with the store's loading
- * process and the mask element will be cached for reuse.  For all other elements, this mask will replace the
- * element's Updater load indicator and will be destroyed after the initial load.
- * <p>Example usage:</p>
- *<pre><code>
-// Basic mask:
-var myMask = new Ext.LoadMask(Ext.getBody(), {msg:"Please wait..."});
-myMask.show();
-</code></pre>
- * @constructor
- * Create a new LoadMask
- * @param {Mixed} el The element or DOM node, or its id
- * @param {Object} config The config object
