Calculate Elo ratings of MMA fighters

To use, load database.py with python -i database.py

To calculate the Elo rating of a fighter, get the link to the fighter's tapology page (e.g., https://www.tapology.com/fightcenter/fighters/nate-diaz), and use the 'calc' function.

Example:

	$ python -i database.py
	>>> calc('https://www.tapology.com/fightcenter/fighters/nate-diaz')
	https://www.tapology.com/fightcenter/fighters/nate-diaz
	win

Once you have two fighters' Elo ratings, you can compute the probability of one fighter defeating the other with the expected_score function.

	>>> expected_score(2000,1800)
	0.7597469266479578

This means that the probability that a fighter with a rating of 2000 defeats a fighter with a rating of 1800 is about .76.
