fdaeaf26 Adding density model(1), rake task to calculate density(2) ... Browse Code »

(1) We calculate the density of votes over time to see if the catchup
algorithm is having an effect. For each question, there are four types
of prompts (seed vs seed, seed vs nonseed, nonseed vs seed, and nonseed
vs nonseed). Over time, the density of all types of prompts should
converge. This model will allow us to track over time

(2)Rake task will be run every night via a cron job. Simply calculates
and saves the four density records for each question in the db.
