+/**
+ * Prado client-side javascript validation fascade.
+ *
+ * There are 4 basic classes, Validation, ValidationManager, ValidationSummary
+ * and TBaseValidator, that interact together to perform validation.
+ * The <tt>Prado.Validation</tt> class co-ordinates together the
+ * validation scheme and is responsible for maintaining references
+ * to ValidationManagers.
+ *
+ * The ValidationManager class is responsible for maintaining refereneces
+ * to individual validators, validation summaries and their associated
+ * groupings.
+ *
+ * The ValidationSummary take cares of display the validator error messages
+ * as html output or an alert output.
+ *
+ * The TBaseValidator is the base class for all validators and contains
+ * methods to interact with the actual inputs, data type conversion.
+ *
+ * An instance of ValidationManager must be instantiated first for a
+ * particular form before instantiating validators and summaries.
+ *
+ * Usage example: adding a required field to a text box input with
+ * ID "input1" in a form with ID "form1".
+ * <code>
+ * <script type="text/javascript" src="../prado.js"></script>
+ * <script type="text/javascript" src="../validator.js"></script>
+ * <form id="form1" action="...">
+ * <div>
+ * <input type="text" id="input1" />
+ * <span id="validator1" style="display:none; color:red">*</span>
+ * <input type="submit text="submit" />
+ * <script type="text/javascript">
+ * new Prado.ValidationManager({FormID : 'form1'});
+ * var options =
+ * {
+ * ID : 'validator1',
+ * FormID : 'form1',
+ * ErrorMessage : '*',
+ * ControlToValidate : 'input1'
+ * }
+ * new Prado.WebUI.TRequiredFieldValidator(options);
+ * new Prado.WebUI.TValidationSummary({ID:'summary1',FormID:'form1'});
+ *
+ * //watch the form onsubmit event, check validators, stop if not valid.
+ * Event.observe("form1", "submit" function(ev)
+ * {
+ * if(Prado.WebUI.Validation.isValid("form1") == false)
+ * Event.stop(ev);
+ * });
+ * </script>
+ * </div>
+ * </form>
