initialize them, you must run:

    git submodule init
    git submodule update

TODO
----

 * Add maven goal to avoid manual call to git submodule init.
 * Make hpack-test-case update itself from git, and run new tests.
 * Add maven goal to generate stories and a pull request to hpack-test-case
   to have others validate our output.
