Add a new class, JDBReverseStringHelper, which encapsulates the reverse
string functionality so that it is no longer a concern for the view
controller.
Update the test case to work with the updated implementation. Add a few new
test cases.
Move the various test cases to their own methods to make it all more modular
and readable.
Moving the UI element properties in the view controller to the header file
so that they are publicly accessible. Now I can access them from the test
case.
Add a test case that actually creates the main view controller and runs
through the standard use case.
