%%  Test script for classdef OOP.
%%  Requires the path to contain the test classes.
%%
%%  Note: This script and all classes are also intended to run
%%        in MATLAB to test compatibility.  Don't break that!
%%
%%  To Do:  This script tests to ensure that things done correctly work
%%          correctly.  It should also check that things done incorrectly
%%          error properly.
%%
%%  The classes used for the tests reside in the test/classdef with others
%%  in the test directory.
%%
%%  The classes provide the ability to test most of the major features
%%  of the classdef OOP facilities.  There are a number of classes, mostly
%%  kind of the same, that create a hierarchy.
