Get Clients and Enrolments for a Staff member. 

This is a listing of all Enrolments for which the Staff Member has a role, where the Enrolment starts within a date range. This function also returns the client (student) linked to the enrolment, and details of the role of the staff member. 

A date range is passed as two parameters, xsdStart and xsdEnd, which define the end points of the date range. These are DateTime objects where the time component is significant. They must be populated with sensible dates (Start > End), otherwise, an input error results. 

Each resulting item is refered to as an Enrolment Staff item. 

Each Enrolment Staff item is represented by a TEnroStaff. The collection of Enrolment Staff items is represented by a List of TEnroStaff. 

Each TEnroStaff item contains information on the Client, the Enrolment and the Staff Member's role under the Contract. 

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