-/**

- * 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>

- * </code>
