Logrithmic league ranking system

Algorithm
---------
A player's score for a tournament is based on two
variables:
1. The size of the tournament, and
2. Where the player finished in the standings.

The score is computed using the following algorithm:
score = ln((p + 1) / f)

where

p = the participant count for the tournament and
f = the player's finish in the standings

Overall score is the average of all tournament scores.

Examples
--------
Malcolm finishes 7th in a 17 player tournament.
Malcolm receives 0.94 points:
. ln((17 + 1) / 7)

Fair and balanced rankings system.
Rewards players for higher finishes.
Rewards players for doing better in bigger tournaments.
Does not penalize players for missing a tournament.
