v0.3.0

• TableFactory() init now expects an optional sa.Metadata() object tf = TableFactory(metadata=sa.Metadata()). If not passed, it will create a metadata automatically which you can access via tf.metadata.
• No longer need to call the factory with sa.Metadata() object. i.e. tf("tablename", metadata) should now be tf("tablename").
