Codeigniter + MongoDB

[eluser]Unknown[/eluser]
I have been working with CodeIgniter for quite a while and eventually I ran into a project where the customer wanted to use MongoDB. At first I thought about writing a database driver, but then I realized that would never work because the drivers are based off of SQL logic, but MongoDB is a NoSQL style document database. I eventually came across Alex Bilbie's MongoDB plugin but found that it lacked the functionality I required, so I decided to use his wonderful code as a starting point and improve/extend from there. The resulting code can be found on github: http://github.com/kyledye/MongoDB-CodeIgniter-Driver

Please let me know what you think!
