rateLimited: function()
auditCount: function(access_token, tag, since)
Use this function to get the count of a particular tag in the audit trail. If you pass the optional since parameter it will limit the count to number of audit trail entries since that time. Whatever is passed with the since parameter will be passed to moment(since) to build a date object directly so you can use any of the valid parse objects for moment
