// TODO:  Follow these steps to enable the Ribbon (XML) item:

// 1: Copy the following code block into the ThisAddin, ThisWorkbook, or ThisDocument class.

//  protected override Microsoft.Office.Core.IRibbonExtensibility CreateRibbonExtensibilityObject()
//  {
//      return new Ribbon();
//  }

// 2. Create callback methods in the "Ribbon Callbacks" region of this class to handle user
//    actions, such as clicking a button. Note: if you have exported this Ribbon from the Ribbon designer,
//    move your code from the event handlers to the callback methods and modify the code to work with the
//    Ribbon extensibility (RibbonX) programming model.

// 3. Assign attributes to the control tags in the Ribbon XML file to identify the appropriate callback methods in your code.  

// For more information, see the Ribbon XML documentation in the Visual Studio Tools for Office Help.
