Delete a Web Waitlist. 

A Web Waitlist ID (webWaitlistId) is passed as a parameter. This should be the ID returned by the AddClientWebWaitlist function used to create the web waitlist. 

Successful execution of this function removes applicatable records from the WEBWAITLIST, WEBCLIENT, WEBCLIENTAVETMISS, WCAVDISA and WCAVPRED tables. 

A token is passed for authentication. If the authentication fails, or other errors occur, nothing is deleted. The result of the authentication is represented by a TAuthenticate object. 

Requires a valid registration key entry for the Short Courses feature. 

This function has security level "Protected", and can only be accessed by users that have explicitly been granted permission to the API, or users with access to the "API Functions" feature in the VETtrak application.
