Fluent insert

I have looked to the driver API which is better than Hector. Thank you for that.

I think you can make a better API.  I'm not expecting the pull request being accepted, it's just an example to help you make a better API.

Arrays and "Stuff..." are really annoying to use. So i recommend to try to remove it from all public API methods or at least propose an alternative API for dynamicaly built statements.

If this example is accepted, I can finish the job by improving the rest of the Query API the same way (for Update, Delete and Select)
