=================
TestStringClass
This is a fairly rigorous test of the str class's functionality.
Because of the fairly global and subtle ramifications of a bug occuring
in this class, it should be run after any changes to the class.
Add more tests as functionality is changed. Tests should include
any possible bounds violation and NULL data tests.
