I'm able to create a Blob, and I see a repository.createCommit call, which requires you to pass in a Tree. However, how do you create the tree for a commit? The createTree() call is not yet implemented.

However, I assume I should be able to do it by hand. And yet, I don't have access to the TreeEntry object to stuff the Blob object into. I also don't seem to have access to Signature for the commit as well. I assume it should look something like (in coffeescript):

repo = gitteh.openRepository('some/path.git')
refHead = repo.getReference('HEAD').resolve()

blob = repo.createBlob({ data: new Buffer("some data") })

// how to access TreeEntry?
treeEntry = new gitteh.TreeEntry({ name: "blob.txt", id: blob.id })

tree = new gitteh.Tree({ entries: [treeEntry] })

// how to get Signature?
commit = repo.createCommit({
  author: new gitteh.Signature({ name: "wil", email: "wil@g.com" })
  parents: [refHead.target]
  message: "some commit message"
  tree: tree
})

And also, this seems like you have to recreate the entire tree in order to commit. That seems like a pain given that usually you just want to commit changed files. How do you commit changed files?
