*
* Implementation Note:
*
* Ideally this class would be extended by AdminCommand's that need these
* services. The problem is getting the values out of the habitat. The ctor
* call would be TOO EARLY in the derived classes. The values are injected AFTER
* construction. We can't easily inject here -- because we don't want this class
* to be a Service.
* We could do it by having the derived class call a set method in here but that
* gets very messy as we have to make sure we are in a valid state for every single
* method call.
