// jQuery Form Validation
// A Parry 2006
//
// This JS only validates, and passes the result to a function "showStatus" - which 
// can be overwritten on a field-by-field basis id necc.
//
// Fields are added to the validator object to either validate onBlur
// or to be stored and validated later (or a mix of both)
//
// example calls
//  <script type="text/javascript">
//    validator.init(function(){
//      $(document).ready(function() {
//        $('#username').validate("{'type':'blur','validation':'notnull'}");
//        $('#email').validate("{'type':'store', 'validation':'email'}");
//        $('#something').validate("{'type':'store', 'validation':'postcode'}");
//        $('#check').validate("{'type':'checkall','callback':'showStatus2'}");
//      });
//    });
//  </script>
