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.

@zenhack, @gsilvis, @lokI8, @ryabouza  
the folder where the log file is created doesn't exist until the program runs.. would a condition such as:

	if 'feedData.log' not in os.listdir(path+'/data/'):
		logging.basicConfig(filename=path+'/data/feedData.log',level=logging.INFO)

be acceptable, as it would configure the logger only the first time the program is ran?
