* This plugin can disable and apply a disable class to any type of html control that can support a click event from it. 
* It has built in support for micorsoft validation testing, showing a waitui and clearing watermarks on click.
* 
*   OPTIONS available for overriding
*   disableAll - allows all controls with the disableonclick= true to be disabled regardless of group or location
*   clearWatermarksCallout - allows for a function callout to a clearwatermarks method. to be used with other jquery watermark plugins
*   waituiCallout - allows for a function callout to a waitui method or event which can do what ever you like between the client click and postback
*   activeClass - active class used on control if any
*   inactiveClass: - inactive class applied on disable
*   resetTimer - time in milliseconds i wait to reset the form controls if validation fails
*   useDisableAttribute - flag to determine if i should also apply the  disable attribute or just the classes
*   groupName - you can apply groupname based on a container level call to ensure all controls with a disableonclick are fired together. optionally you can assign the
*   groupname on the control itset as a custom attribute. which will allow for more specific control of the groupings
*
* Example Usage
