I wish to join a table with the UserList class.

I have tried addToQuery which does the join fine, but the columns are unaffected as a UserInfo object is returned.

I have tried to extend the UserList class but this fails as the parent class then forces all returned objects to be of type UserInfo.

I could extend ItemList or DatabaseItemList but this will add to my headaches because I will loose all the user filter functions in UserList

I am so close but so far I fear.
