Add an Web Employer Contact. 

A Web Employer Contact is a web client who is a contact person for a company making an Employer Enrolment. 

AddWebEmployerContact creates a web Client who links to the Web Employer and the Employer Web Enrolment. 

A Web Enrolment ID (iWebe_ID) is passed as a parameter. This should be the ID returned by the AddEmployerWebEnrolment function. 

Details of the Web Client (sSurname, sGiven Name, DOB and sCode) are supplied as parameters. If a non-empty string is supplied as sCode, an attempt is made to match the web client details with an existing client record in the VETtrak database. 

AddWebEmployerContact behaves in a similar way to AddWebEmployee, the difference being that the web client generated is flagged as a contact, rather than a student. 

A token is passed for authentication. If the authentication fails, or other errors occur, no web client is created. The result of the authentication is represented by a TAuthenticate object. 

Requires a valid registration key entry for the Bookings feature. 

This function has security level "Protected", and can only be accessed by users that have explicitly been granted permission to the API.
