Revision Walking about node-gitteh

@vdurbha

This was present in the original implementation of gitteh, I haven't yet gotten around to re-adding it in the latest version (which was nearly a complete rewrite).

Technically you can still revision walk without the actual revwalk API however. All you need to do is grab HEAD and follow it's parent commits. That being said, I do want to re-add this as soon as possible.

I'll keep this issue open and update once revwalk returns.

Great. Thanks. Yes I was able to grab HEAD and follow the parents. I guess the only reason to use Walker would be to sort the entries I guess. I'll give it a shot when it becomes available.

This is being done as part of the cleanup, see #29.

I needed such functionality and implemented it myself in a separate package — https://github.com/andreypopp/gitteh-log/blob/master/index.coffee

See previousCommitsSeq function which returns a lazy sequence (provided by reduced package) of commits previous to a provided one as an argument. it's not as straightforward as simple event emitter but I've found lazy sequences to be much more nicer API.
