  /**
   * @class Ext.MessageBox
   * <p>Utility class for generating different styles of message boxes.  The alias Ext.Msg can also be used.<p/>
   * <p>Note that the MessageBox is asynchronous.  Unlike a regular JavaScript <code>alert</code> (which will halt
   * browser execution), showing a MessageBox will not cause the code to stop.  For this reason, if you have code
   * that should only run <em>after</em> some user feedback from the MessageBox, you must use a callback function
   * (see the <code>function</code> parameter for {@link #show} for more details).</p>
   * <p>Example usage:</p>
   *<pre><code>
  // Basic alert:
  Ext.Msg.alert('Status', 'Changes saved successfully.');
  
  // Prompt for user data and process the result using a callback:
  Ext.Msg.prompt('Name', 'Please enter your name:', function(btn, text){
      if (btn == 'ok'){
          // process text value and close...
      }
  });
  
  // Show a dialog using config options:
  Ext.Msg.show({
     title:'Save Changes?',
     msg: 'You are closing a tab that has unsaved changes. Would you like to save your changes?',
     buttons: Ext.Msg.YESNOCANCEL,
     fn: processResult,
     animEl: 'elId',
     icon: Ext.MessageBox.QUESTION
  });
  </code></pre>
