@busbey Sean, this is an updated PR integrating Crail (crail.apache.org) we discussed last year. Do you think the PR will be merged soon, or are there an missing pieces or issues you would like me to address?

This is real close.

• Move classes into a crail specific package
• Make binding respect configuration of table name
• Use a logging framework instead of System.out

That said, this has been a long time coming so I might just push a commit with the needed changes if I get some time.

Ok, thanks, I'll should have this ready next week!

The PR is ready for review.

• Moved the classes to a crail specific package
• Setting table based on properties
• Using logging framework instead of System.out
• Also added one new parameter to control whether or not the keys can be enumerated
