Subject: Remove runtests.py and naive_trace_reader

These are outdated and I don't feel like maintaining them.

-# Description
-###############################################################################
-
-# trace_reader(files) returns an iterator which produces records
-# OUT OF ORDER from the files given. (the param is a list of files.)
-#
-# The non-naive trace_reader has a lot of complex logic which attempts to
-# produce records in order (even though they are being pulled from multiple
-# files which themselves are only approximately ordered). This trace_reader
-# attempts to be as simple as possible and is used in the unit tests to
-# make sure the total number of records read by the normal trace_reader is
-# the same as the number of records read by this one.
