change the description to make sense
add method to recalculate stats private

still more to do here
rake task and process stat service started
Add processed stat table, migration and schema updated
processed stat service - do actual work
add migration for scoring rules to league
db migrate ran for leagues table
match ups method that returns both away and home matchups
Precalculate stats - use them in views and models

have to pass league around - but that is ok with me for now
Merge branch 'pre-calc-stats' into develop
