Starting point for editing table rows

Turns out what I was looking to do was a more complex subjec than I thought. I ended up comparing Nested Sets and MPTree. I ultimately went with the nested sets solution found here: http://ellislab.com/forums/viewthread/47671/

I think MPTtree (http://ellislab.com/forums/viewthread/74114/#394395) has a more advanced underlying class, but they both use the same method, and Thunder UK's nested set categories_demo was scarily almost exactly what I was looking for.

I'm still working on my solution, but I'm using the CI Ajax class (found in the wiki) that builds upon prototype. I also integrated greybox (http://www.orangoo.com/labs/GreyBox/), which is really a great tool kit if you don't want to have to worry about updating divs and stylesheets.
