/**
 * jQuery.fn.verify
 *
 * - url        The URL to send the POST/GET AJAX request to
 * - verifying  The CSS class to toggle while verification is taking place
 * - valid      The CSS class to toggle if verification is successful
 * - invalid    The CSS class to toggle if verification fails
 * - method     Set to either get or post
 * 
 * The url should expect to receive either a GET or POST variable named 
 * 'value'. In that will be the value of the input this is attached to. It 
 * should then respond with either '1' or '0'. '1' means that the value is 
 * valid, while '0' (or any non '1' response) means the value is invalid.
 * 
 * Additionally, the classes verifying + 'Parent', valid + 'Parent', and
 * invalid + 'Parent' are toggled appropriately. This allows you to add a
 * background icon to the container element if you so wish for instance.
