Thanks to all who sent comments on the last version of the muon digit container
design. And thanks to Hong Ma a long discussion about their IdentifiableContainer
(formerly DigitContainer). I have posted an updated design at the usual location:

  http://www.usatlas.bnl.gov/~dladams/mudigi

I now understand that the model of Ma and Meesen is an implementation and
should not be part of our interface. The new design of the muon digit container
distinguishes between the granularity of the the interface and that of the
implementation (based on the Ma and Meesen persistence mechanism). Different
choices are made for the two: ROD for the implementation and module (chamber)
for the interface. The interface is discussed as a new design issue.

Once again I invite comments especially on the decision to hide the Ma and
Meesen implementation and the choices made for the user interface.
