title: How to get URL of GWT EntryPoint?
body: <p>I'd like to create a Hyperlink from one GWT module to another. Instead of hard-coding a URL string, I want to programmatically convert a module class to its associated URL so that when the class is refactored it does not result in broken links. Any ideas?</p>
  
  <p><strong>UPDATE</strong>: I want to be able to look up the URL for EntryPoint "B" from inside EntryPoint "A".</p>
