Changed User get_friends method to return .items() instead of .pages(), allowing flask to iterate for friend in friendlist.

changed .pages() to .items(), list of friend IDs now iterable in flask server
print friend for friend in friendlist
set friend.USER_SCORE using dummy scoring script
Add manual pagination function to flask app, import itertools.

Using itertools library, divide friends_ids into pages of 100 friends ids each.
This is because lookup_users function (Twitter GET request) can only process 100 ids per request.
Manual pagination works.
Fixed exception error, updated name of friends_ids variable in flask and friends.py, test in ipython nb

Renamed friend_ids to friends_ids, because my continual use of 'friends_ids' kept causing NameErrors
Renamed function in friends.py
In flask, my except statement was not showing errors, as an exception would simply cause page to render
Renamed jinja variable to "display" so that errors can display on the html page as well
Display = friends if 'try' succeeds, display = error if exception
Moved pagination function into User class.

Took pagination function out of flask and put it into user class, keeping operations on user friends contained within User.
Renamed 'ids' parameter to f_ids in keeping with my own naming convention elsewhere in friends.py
Write docstrings for paginate_friends, lookup_friends, and get_top_influencers User methods.

Include notes on API limits. I'm leaving these as parameters to methods, however, in case API rate limits change.
Clean up commented-out code in flask_server, create user object for each friend in page

When iterating through pages of paginated friends, create a User instance for ech friend and give it a score.
When rendering index.html, pass in friendlist as a list of friend scores, rather than as a list of friend objects.
Update docstrings in friends.py and correct indentation
Working test version of scorefriends in ipython notebook.
