[CentralOH] Code to Refactor

[Eric Floehr]

The need to return variable lengths pretty much rules out a generator.

If s is a string, you could just use a memory file, i.e. StringIO:

import cStringIO # Use cStringIO over StringIO for speed

stringfile = cStringIO.StringIO(s)
next_n = stringfile.read(n)
