Extend debugging to DatabaseApi class

Currently when ``debugMode`` is set on ``class DatabaseApi``, verbose ``console`` logging occurs only for ``class Table`` methods.  We would like to extend this option to ``class DatabaseApi``.

Tasks at hand:
- [ ] Add ``class DatabaseApi`` specific methods to ``class DbDebugger``
- [ ] Update ``class DatabaseApi`` to optionally instantiate and call relevant ``class DbDebugger`` methods
