Extension on Tweepy twitter streamer that stores retweet
information about users and their connections to one another

Twitter streamer that finds retweets and stores the username of both
the retweeter and the original tweeter in a CSV file. Handles file
management so the data is split across multiple CSV files.

sep: separator for CSV data, defaults to characters unlikely to be
together in a twitter username

On call, opens a new file to be used in output and closes any open file.
Manages the filename by making sure never to overwrite a previously created file.
Sets the open file as an attribute for usage across the class.

File name selector helper function. Checks for existing files and

base filename directory.

When receiving data from the stream, check to see if it is a retweet (label RT),
if it is, extract the username and check to see if the original tweet information
is available. If so, store the usernames for the original tweeter and the retweeter
so we can build a network graph. Also manages how many tweets are currently stored in
each file.
