Inheritance Project

I will discuss the following modules, and we will examine them and their use.

1) counters.py: updated: we will run by itself and run 
2) inheritancesample.py: 3 do-nothing classes to run with the inheritancetool
3) inheritancetool.py  : a function that find the location of an attribute for
                           an instance (simulating how Python uses inheritance)
4) pdefaultdict.py     : how to implement defaultdict from dict via inheritance
5) privacy.py          : a class to use as a base class to simulate private
                           instance variables
6) whereisdriver.py    : driver for the where_is function in the inheritancetool
