 * EXAMPLES OF USE:
 *
 * Get the domain name (host) from the current page URL
 * jQuery.url.attr("host")
 *
 * Get the query string value for 'item' for the current page
 * jQuery.url.param("item") // null if it doesn't exist
 *
 * Get the second segment of the URI of the current page
 * jQuery.url.segment(2) // null if it doesn't exist
 *
 * Get the protocol of a manually passed in URL
 * jQuery.url.setUrl("http://allmarkedup.com/").attr("protocol") // returns 'http'
