Remove option for categories from get_flashed_messages
Add test set of users, redirect to prefetched route. This allows me to show viewers users who have very large numbers of friends - the "whales" of my app.
Clean up and refactor display_friends, reducing the number of try/except blocks and moving friend_scores to the top of the function for easy tracking.
Added test cases to flask, use time.sleep to allow front-end progress bar to load. Set time to wait as global variable.
Remove timeout in app.js, as the 100ms callback time was causing a jump in the display
Modify flask_server to conform to PEP8 standards. WIP: remove long json strings to pickle.
Add params to tweepy API object to set number of retries, whether or not to wait on rate limit (currently false, but easily changeable to true).
Add comment to indicate meaning of NUM_RETRIES
Created pickle files to hold demo case friend scores, to be loaded and returned from prefetch app route.

 - Files created by printing out json_scores from an initial processing of the person's friends
 - Pickle dictionary output of json_scores
Prefetched working. Add glennbeck to test set. Replace prefetched json with pickle.load and filename generated by test-set user's screen name.
Removed outdated import of check_rate_limit -- will re-import when I incorporate rate limit checking into error handling
Moved MAX_NUM_TWEETS and MAX_NUM_FRIENDS -- variables that determine program output -- to the top of flask_server, out from friends.py. These variables describe the program's function more than they describe a User object.
Update friends.py following PEP8 guidelines. Remove main() and connect_to_API function, which are unnecessary since friends.py is never called from the command line.
Make class variables for User lower-case. Change in friends.py and also in flask_server, where instance variables are assigned.
Delete old or unnecessary comments from friends.py. Remove hashtags_count, which was a helper function for scoring timelines before using the classifier in score().
Experiment with making get_friends_ids more self-reliant, using class variable central_user as the user for whom to get friend ids.
WIP
Move check_rate_limit into flask_server, where it's closer to the logic of error handling and checking rate limits. Lowercase friend.SCORE to friend.score.
Fixed several bugs that were preventing functioning visualization, notably in class vars left capitalized in friends.py, and an if-statement that was returning average_score of 0.

 - Removed if-statement that was checking if probs are greater than 0. (This was meant to handle an error that appeared earlier, which itself was due to the all-caps naming switch)
 - Lowercased caps in User __init__
 - Renamed method to score_user to avoid confusion with the class var 'score.'
Added screencaps to README.
