Takes any given comment object and returns the object of the
original post, no matter how far up the chain it is. This is
a very time-intensive function because of how Reddit handles
rate limiting and the fact that you can't just request the
top parent -- you have to just loop your way to the top.

:param r: the instantiated reddit object
:return: submission object of the top post.
