TestClass

classdef TestClass < handle
   %TESTCLASS used to demonstrate the cloning of an object
   %   Since TestClass inherits reference behaviour from the 'handle' class
   %   you will only create a shallow copy of an instance of this class by
   %   specifying b = a; where 'a' is an instance of testClass. Effectively
   %   'a' and 'b' are references to the same object.
   %   This class contains a constructor and a method which both produce
   %   clones (deep copies) of an object of its kind.
