Writing MassDOT data feeds locally

changes that I am working on:
  - reading URL's and feednames from a configuration file, instead of hardcoding these for each feed
  - removing script 'collectData.sh'; using only store.py to continuously pull the data

this version shows data being pulled only from the 'travelTimes' feed.

I would move the call to basicConfig out of this method, and jus to it once on program startup.
