wrote code to get eval.py working with new format of read_nfl.py.  still lingering issues with fetching of oracle projections where projections are incomplete due to tables spanning more than one page online.
Merge branch 'master' of https://github.com/hughec/ff_predict

Conflicts:
	eval.py
	gather_nfl.py
	read_nfl.py
	read_nfl.pyc
Corrected conflicts.
updated gather_nfl to gather defensive data by team. that is, the function gather_teams gets the stats for all players who played against a given team in a given week
updated read_nfl with a function to read team defensive stats from team files.  also made changes to the read_player_data function to create a dictionary for player stats, and minor changes to the extract_game_stats function to include stats for carries, receptions, etc.
