This is a simple script to get all of your likes from Facebook via their API for my blog post: Social APIs for Social Evil - http://caseysoftware.com/blog/social-apis-for-social-evil

 * This file has a total of three values:
 *  - The App ID and App Secret received when you create a new Application.
 *  - The person/application-specific Access Token, normally granted via the OAuth process.
 *
 * For simplicity here, I've skipped the OAuth process and retrieved my Access Token via the
 *   Graph API Explorer from the Developer Portal: https://developers.facebook.com

/*
 * Using the user_id from above, let's look at my likes.
 *
 * One of the things to be aware of is that Facebook uses cursor-based paginated results. It means that
 *   instead of getting one *long* list of whatever data, you're going to get a page with a URL pointing
 *   to the next page. You request the next page and repeat as long as there's still another page.
