OK - that was weird, and took some debugging.
I knew there was *something* about scope to deal with here.
I'm aggragating the database object into a base class, and then creating
other classes that "extend" that base class.
HOWEVER, in order to do that, I had to move the instantiation(?) of the
database class into the extended class. When I had it in the base
class, the class that extended it could not see the database properties
and functions.
Whew.
