Suggestion: correlate methods with resource rate limits in the documentation

[zedmas...@gmail.com]

Hi, first off, thanks for the python-twitter team for making this awesome module!  It's been really helpful.  I apologize if my terminology is a bit off, I'm fairly new to coding, and self-taught.  Hopefully you get the gist of what I'm saying.

One issue I've run into is figuring out which rate limit applies to which method in the python-twitter module.  Mostly, I've been able to just download a rate limit dictionary using Api.GetRateLimitStatus(), and make guesses as to which limit applies to which method.  However, some methods are entirely unclear to me, such as GetReplies().  I'm assuming this uses data from /statuses/mentions_timeline, and figures out which are replies?  Regardless, it would be very handy if the documentation could be amended to say something like "Method X depends on rate limit resource Y..."
