playing around with algorithm to get artist/title

simple cases are fairly easy, next step is go test an actual upload from
each channel we propose to track

this commit closes issue #48
----------------------------

all unit tests in file are passing.  some random testing will be needed
to identify patterns of naming not yet anticipated or seen, however the
rules in this routine should be working a very large majority of the
time.

on failure, this routine should return ('',input_given), however all
cases of dirty input have not been tested to ensure it always fails
gracefully
remove namedtuple, better comments and flow
