> In the process of creating the a ruby version of the query server, I wrote these to determine
it was working correctly. Even though the repository for the ruby query server contains its
own test suite, I figure these might be welcomed into the main query server specs. If not,
no big deal. They assume the ruby query server's repository is in the same parent directory
as couchdb.
