/** A select cycle could be started in Servant mode or it could be started by
* the AddMembers command. The AddMembers command sets the id of the parent
* group (ie. the group to which child members will be added). Control is then
* passed to a selection view where the child group members will be selected
* for addition. When the selection has been completed by the user, the
* DoneWithSelection command will be invoked where the selected children
* group members are actually processed. Alternatively, the CancelSelection
* command is invoked to cancel the selection process and reset the mode and
* view control parameters.
