anchor.diff:  you normally put in there for bootstrapping an UberFire app? Let's
   first create a panel and then come back to that question.
   
  -== Create a panel
  +== Create a Workbench Screen
   
   UberFire interfaces are made up of a few fundamental building blocks:
  -Widgets, Panels, Menu Bars, Tool Bars, and Perspectives. Panels can
  -contain Widgets and other Panels, and Perspectives contain Panels, an
  -optional Menu Bar, and an optional Tool Bar. Perspectives split up the
  -screen into multiple resizeable regions, and end users can drag and
  -drop Panels between these regions to customize their workspace. Use of
  -Perspectives is optional, so we'll leave them for later.

  -To create your first panel, create the file
  -`src/main/java/com/mycompany/uftutorial/client/PanelOne.java`:
  +Widgets, Layout Panels, Screens, Workbench Panels, Menu Bars, Tool
  +Bars, and Perspectives. Layout Panels can contain Widgets and other
