Downloads section added

We just added a new downloads section (http://www.nth-iteration.com/downloads/) where we point to resources (software and data) created by the lab.

We are also publishing a dataset of clicks on Persuasive messages. This is a dataset in which the persuasive strategies where selected uniformly randomly, and the dataset can thus be used for the offline evaluation of bandit policies (although, mind the complexities in the data collection – see the README of the download itself).

We hope to add more resources as time goes on.
