## SocialHistory.js
/*
 * Social Limit - Only the social you care about.
 *
 * Enables your site to know which social bookmarking badges to display to your
 * visitors. It tells you all social sites the user has gone to, or you can
 * query for a specific one.
 *
 * For example:
 *
 *    var sl = SocialHistory();
 *    alert( sl.doesVisit("Digg") ); // Returns true/false, -1 if unknown.
 *    var listOfVisitedSites = sl.visitedSites();
 *    var checkedSites = sl.checkedSites();
 *
 * If you want to add more sites to check, you can pass that in as a dictionary
 * to History:
 *
 *    var more = { "Humanized": "http://humanized.com",
 *                 "Azarask.in": ["http://azarask.in", "http://azarask.in/blog"]
 *               };
 *    var sl = SocialHistory(more);
 *    alert( sl.doesVisit("Humanized") );
 *
 * For a list of built-in sites, see the sites variable below.
