/**
 * Validates a single form.
 *
 * The normal behaviour is to validate a form when a submit button is clicked or
 * the user presses enter when an input of that form is focused.
 *
 * It is also possible to validate each individual element of that form, eg. on blur or keyup.
 *
 * @example $("#myform").validate();
 * @before <form id="myform">
 *   <input name="firstname" class="{required:true}" />
 * </form>
 * @desc Validates a form on submit. Rules are read from metadata.
 *
 * @example $("input").validate({
 *      event: "blur",
 *      success: "valid"
 * });
 * @desc Validates all input elements on blur event (when the element looses focus).
 * Adds a class "valid" to all error labels when the elements are valid and keeps showing
 * them.
 *
 * @example $("#myform").validate({
 *   submitHandler: function(form) {
 *      $(form).ajaxSubmit();
 *   }
 * });
 * @desc Uses form plugin's ajaxSubmit method to handle the form submit, while preventing
 * the default submit.
 *
 * @example $("#myform").validate({
 *  event: "keyup"
 *  rules: {
 *      "first-name": "required",
 *      age: {
 *          required: "#firstname:blank",
 *          number: true,
 *          minValue: 3
 *      },
 *      password: {
 *          required: function() {
 *              return $("#age").val() < 18;
 *          },
 *          minLength: 5,
 *          maxLength: 32
 *      }
 *  },
 *  messages: {
 *      password: {
 *          required: function(element, validator) {
 *              return "Your password is required because with " + $("#age").val() + ", you are not old enough yet."
 *          },
 *          minLength: "Please enter a password at least 5 characters long.",
 *          maxLength: "Please enter a password no longer then 32 characters long."
 *      },
 *      age: "Please specify your age as a number (at least 3)."
 *  }
 * });
 * @desc Validate a form on submit and each element on keyup. Rules are specified
 * for three elements, and a message is customized for the "password" and the
 * "age" elements. Inline rules are ignored. The password is only required when the age is lower
 * then 18. The age is only required when the firstname is blank. Note that "first-name" is quoted, because
 * it isn't a valid javascript identifier. "first-name": "required" also uses a shortcut replacement for
 * { required: true }. That works for all trivial validations that expect no more then a boolean-true argument.
 * The required-message for password is specified as a function to use runtime customization.
 *
 * @example $("#myform").validate({
 *   errorClass: "invalid",
 *   errorLabelContainer: $("#messageBox"),
 *   wrapper: "li"
 * });
 * @before <ul id="messageBox"></ul>
 * <form id="myform" action="/login" method="post">
 *   <label>Firstname</label>
 *   <input name="fname" class="{required:true}" />
 *   <label>Lastname</label>
 *   <input name="lname" title="Your lastname, please!" class="{required:true}" />
 * </form>
 * @result <ul id="messageBox">
 *   <li><label for="fname" class="invalid">Please specify your firstname!</label></li>
 *   <li><label for="lname" class="invalid">Your lastname, please!</label></li>
 * </ul>
 * <form id="myform" action="/login" method="post">
 *   <label>Firstname</label>
 *   <input name="fname" class="{required:true} invalid" />
 *   <label>Lastname</label>
 *   <input name="lname" title="Your lastname, please!" class="{required:true} invalid" />
 * </form>
 * @desc Validates a form on submit. The class used to search, create and display
 * error labels is changed to "invalid". This is also added to invalid elements.
 *
 * All error labels are displayed inside an unordered list with the ID "messageBox", as
 * specified by the jQuery object passed as errorContainer option. All error elements
 * are wrapped inside an li element, to create a list of messages.
 *
 * To ease the setup of the form, debug option is set to true, preventing a submit
 * of the form no matter of being valid or not.
 *
 *
 * @example $("#myform").validate({
 *  errorPlacement: function(error, element) {
 *      error.appendTo( element.parent("td").next("td") );
 *  },
 *  success: function(label) {
 *      label.text("ok!").addClass("success");
 *  }
 * });
 * @before <form id="myform" action="/login" method="post">
 *  <table>
 *      <tr>
 *          <td><label>Firstname</label>
 *          <td><input name="fname" class="{required:true}" value="Pete" /></td>
 *          <td></td>
 *      </tr>
 *      <tr>
 *          <td><label>Lastname</label></td>
 *          <td><input name="lname" title="Your lastname, please!" class="{required:true}" /></td>
 *          <td></td>
 *      </tr>
 *  </table>
 * </form>
 * @result <form id="myform" action="/login" method="post">
 *  <table>
 *      <tr>
 *          <td><label>Firstname</label>
 *          <td><input name="fname" class="{required:true}" value="Pete" /></td>
 *          <td><label for="fname" class="invalid success">ok!</label></td>
 *      </tr>
 *      <tr>
 *          <td><label>Lastname</label></td>
 *          <td><input name="lname" title="Your lastname, please!" class="{required:true}" /></td>
 *          <td><label for="lname" class="invalid">Your lastname, please!</label></td>
 *      </tr>
 *  </table>
 * </form>
 * @desc Validates a form on submit. Customizes the placement of the generated labels
 * by appending them to the next table cell. Displays "ok!" for valid elements and adds a class
 * "success" to the message (the class "invalid" is kept to identify the error label).
 *
 * @example $("#myform").validate({
 *   errorContainer: $("#messageBox1, #messageBox2"),
 *   errorLabelContainer: $("#messageBox1 ul"),
 *   wrapper: "li",
 * });
 * @before <div id="messageBox1">
 *   <h3>The are errors in your form!</h3>
 *   <ul></ul>
 * </div>
 * <form id="myform" action="/login" method="post">
 *   <label>Firstname</label>
 *   <input name="fname" class="{required:true}" />
 *   <label>Lastname</label>
 *   <input name="lname" title="Your lastname, please!" class="{required:true}" />
 * </form>
 * <div id="messageBox2">
 *   <h3>The are errors in your form, see details above!</h3>
 * </div>
 * @result <ul id="messageBox">
 *   <li><label for="fname" class="error">Please specify your firstname!</label></li>
 *   <li><label for="lname" class="error">Your lastname, please!</label></li>
 * </ul>
 * <form id="myform" action="/login" method="post">
 *   <label>Firstname</label>
 *   <input name="fname" class="{required:true} error" />
 *   <label>Lastname</label>
 *   <input name="lname" title="Your lastname, please!" class="{required:true} error" />
 * </form>
 * @desc Validates a form on submit. Similar to the above example, but with an additional
 * container for error messages. The elements given as the errorContainer are all shown
 * and hidden when errors occur. But the error labels themselve are added to the element(s)
 * given as errorLabelContainer, here an unordered list. Therefore the error labels are
 * also wrapped into li elements (wrapper option).
 *
 * @param Map options Optional settings to configure validation
 * @option String errorClass Use this class to look for existing error labels and add it to
 *      invalid elements. Default: "error"
 * @option String wrapper Wrap error labels with the specified element, eg "li". Default: none
 * @option Boolean debug If true, the form is not submitted and certain errors are display on the console (requires Firebug or Firebug lite). Default: none
 * @option Boolean focusInvalid Focus the last active or first invalid element on submit or via validator.focusInvalid(). Default: true
 * @option Function submitHandler Callback for handling the actual
 *      submit when the form is valid. Gets the form as the only argmument. Default: normal form submit
 * @option Map<String, Object> messages Key/value pairs defining custom messages.
 *      Key is the name of an element, value the message to display for that element. Instead of
 *      a plain message another map with specific messages for each rule can be used.
 *      Can be specified for one or more elements. Overrides the title attribute of an element.
 *      Each message can be a String or a Function. The Function is called with the element
 *      as the first and the validator as the second argument and must return a String to display as the message
 *      for that element.
 *      Default: none, the default message for the method is used.
 * @option Map<String, Object> rules Key/value pairs defining custom rules.
 *      Key is the ID or name (for radio/checkbox inputs) of an element,
 *      value is an object consisting of rule/parameter pairs, eg. {required: true, min: 3}.
 *      Once specified, metadata rules are completely ignored.
 *      Default: none, rules are read from metadata via metadata plugin
 * @option Boolean onsubmit Validate the form on submit. Set to false to use only other
 *      events for validation (option event). Default: true
 * @option String meta In case you use metadata for other plugins, too, you
 *      want to wrap your validation rules
 *      into their own object that can be specified via this option. Default: none
 * @option jQuery errorContainer Hide and show this container when validating. Default: none
 * @option jQuery errorLabelContainer Search and append error labels to this container, and show and hide it accordingly. Default: none
 * @option Function showErrors A custom message display handler. Gets the map of errors as the
 *      first argument and a refernce to the validator object as the second.
 *      You can trigger (in addition to your own messages) the default behaviour by calling
 *      the defaultShowErrors() method of the validator.
 *      Default: none, uses built-in message disply.
 * @option Function errorPlacement Used to customize placement of created error labels.
 *      First argument: jQuery object containing the created error label
 *      Second argument: jQuery object containing the invalid element
 *      Default: Places the error label after the invalid element
 * @option String errorElement The element to use for generated error messages. Default: "label"
 * @option String|Function If specified, the error label is displayed to show a valid element. If 
 *      a String is given, its added as a class to the label. If a Function is given, its called with
 *      the label (as a jQuery object) as its only argument. That can be used to add a text like "ok!".
 *      Default: none
 * @option Boolean focusCleanup If enabled, removes the errorClass from the invalid elements and hides
 *      all errors messages whenever the element is focused. Avoid combination with focusInvalid. Default: false
 * @option String|Element ignore Elements to ignore when validating, simply filtering them out. jQuery's not-method
 *      is used, there everything that is accepted by not() can be passed as this option. Default: None, though inputs of type
 *      submit and reset are always ignored.
 * @opton Boolean onblur Validate elements on blur. If nothing is entered, all rules are skipped, 
 *      except when the field was already marked as invalid. Default: true
 *
 * @name validate
 * @type $.validator
