Memetracker can't pass distance data for more than ~110 content at a time

Memetracker won't cluster more than 110 content at a time. I'm guessing the problem is python/bash has some limition on the length of command line arguments that'll it take (right now with 110 content, memetracker is passing 106375 characters to cluster.py).

My plan right now to work around that is to write the distance info to a temp file in the machinelearningapi directory which the Python script would parse.
