commit to resolve merge conflicts
updated junit tests to work with the new thread classes.  Updated a clean DB_export.sql file containing only 1 course, 18 holes, and 2 previously played games
forgot to actually run the export for the DB on the last commit--this is a commit of the updated DB_export.sql with a clean set of records
updated junit tests, and fixes. All methods in SQLQueries (and sub classes) are tested, except for getUserHistory().  An updated DB is also included
