Get a list of ancestors for an employer. This is effectively the path to the employer through the employer tree. 

Specify the identifier of an employer to get the ancestors for. Returns a list of employers, each one represented by a TEmpl object. The employers are in order from the top-most employer down to the specified employer. Note that the specified division is also included in the return value as the last division in the list. 

A token is passed for authentication. If the authentication fails, or other errors occur, the employers are not returned. The result of the authentication is represented by a TAuthenticate object. 

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