Sped up report generation by a thousand times (probably)
Made report faster
Fixed indent
Made the report even faster
Added one association I missed
And... actually use the new code
More optimizations
Indentation again
Readded a find_each that has no performance impact and will probably save us if we ever do MOOC's
