Branch utility function
Implemented fix for passing of optional arguments. Still needs significant testing before its ready for production
Passing optional arguments is now working correctly for "insert". I imagine there are more cases where I will need to enable them.
Additional changes for parsing optional arguments. Also added some extra testing around a few of the predicates. There is still more work to be done, but at this point the interface should be usable for most things.
Added changes to allow optional arguments for some of the commands.
Updating the release to 0.10
