  This example demonstrates a custom <a>CommandHandler</a>.
  It uses localStorage as the repository for the clipboard, rather than an in-memory global variable.
  It is defined in its own file, as <a href="LocalStorageCommandHandler.ts">LocalStorageCommandHandler.ts</a>.
</p>
<p>
  Try copying and pasting between the above Diagrams, or between tabs/windows that contain Diagrams using LocalStorageCommandHandler.
  Note that when copying and pasting between Diagrams, it will work best if they have similar templates.
