Hi!

I'm trying to use nodegit to build a virtual fs module that fetches its data from a commit in a git repository: https://github.com/papandreou/node-gitfakefs -- it's going fine so far, I've implemented readFile, readdir, and stat.

Next up is adding support for the index. I found repo.openIndex and can get the entries out of it, but from the docs I can't find a way to get the contents of an index entry -- the actual staged contents. Is there a way to accomplish that? Otherwise consider this a feature request :)
