Use tournament log as a classifier

[ianbulovic]

After running a tournament, it would be useful to be able to use the results of the tournament to classify new samples.

• Include complete sample data in tournament log

This is necessary so we can compare the new, unseen data to data with a known ELO.

• Implement strategies to estimate the ELO of a new sample and calculate expected win probability

There is a efficiency/accuracy tradeoff here... a more accurate ELO estimate requires more matches against known data
