API Documentation is here

I expected a method of the form of [1], but it looks like getCommitter and getAuthor return a User. Similarly, I expected [2] when looking for the user.

If there's a way to do this that I'm not aware of, please let me know.

[1] myGHCommit.getCommitter().getDate() and myGHCommit.getAuthor().getDate()
[2] myGHCommit.getCommitter().getUser() and myGHCommit.getAuthor().getUser()
