a parameter hierarchy container directly.  That way, the data
structure is separated from the various ways to fill it.

Having a parser class inherit from a container is certainly not
a good design.  However, it is the simplest way to get rid of
the container implementation and still be 100% backward-compatible.
I will deprecated a few container-related methods in the near
future.

string-based key/value pairs.  Input from streams/files-in-different-formats/
command-lines etc is expected to be implemented in separate parser code.

The usage and implementation is the one from the ConfigParser class.
We may want to discuss whether there are better designs/implementations
for this.
