Command-line based movie recommendation app based on Toby Segaran's Programming Collective Intelligence. Movie recommendations are based on a collaborative filtering algorithm (Pearson similarity). Written in Ruby. Movie recommendations sourced from MovieLens.

To-do:

• sanitize user input (specifically when movie string title isn't in the database)
• refactor algorithm code
• optimize for time
• current algorithm is similar people recommendations, but i'd like to add similar product recommendations
