Initial commit. This code was written by Jagadish Venkatraman.
Cleaned up some indentation issues; added setup.py. Considering replacing use of mysqldb with pymysqldb, which is used elsewhere in the project. Comments are needed everywhere.
Added file mysqldb.py in the hope of removing dependency on MySQLDb.py. The mysqldb.py adds a thin layer to pymysqldb, which we are already requiring in json_to_relation code. No attempt made to integrate mysqldb.py into extract.py, though.
Merge branch 'master' of github.com:Stanford-Online/forum_etl. Datastage was behind, b/c some dev happened on Mono.
Modified setup.py to require pymysql_utils
