 #### Adding Sites ####
 
 This project was built to easily drop in support for new sites. The `site-manager` iterates over all files contained within the `sites` directory, and adds it to the list of available sites. When a request is issued to price-finder to look up a price, it asks each site if the `uri` is supported by the site, and if so, uses that site to find the price.
