     Program to set up for running our REST server.
     We do these things:
         - Attach to the database
         - Initialize our type objects so things like ClientQuery will work...
         - Load the queries into the database from flat files
             Not sure if doing this here makes the best sense, but it
             works, and currently we're the only one who cares about them
             so it seems reasonable -- at the moment ;-)
             Also we're most likely to iterate changing on those relating to the
             REST server, so fixing them just by restarting the REST server seems
             to make a lot of sense (at the moment)
         - Remember the set of queries in the 'allqueries' hash table
