  Simple page for testing gadgets.rpc performance.
  Allows you to add a simulated "gadget" (in this case just a static
  HTML page which loads gadgets.rpc also), and pass some
  specified number of random messages of specified size to
  and from it.

  To use, start up two instances of
  the Shindig Gadgets Server on two separate ports to test
  "real" cross-domain communication, since port is factored
  into the same-domain policy enforced by browsers. One
  server will be used for the container, the other for the gadget.

  If your container on localhost:8080 with gadget on localhost:8081,
  then to load the test load the following in your browser:
  http://localhost:8080/container/rpctest_container.html?localhost:8081

  This test container/gadget pair is configurable via two other options:
  * &gadgetdeferred=1 - tests early-message queueing from container to
    gadget, by preventing attachment of gadget until a button is pressed.
  * &uabackward=1 - tests "incorrect" rpc.js setup in container:
    gadgets.rpc.setAuthToken(...) called before, not after, gadget frame exists.

  These options may be provided in any combination.
