/*************************************************************************
@class: String
This is a first-pass implementation of a String class that uses only C
and basic C++ enhancements to C for its implementation. The purpose of
this class is to work out the basic functionality of the string class as
well as practice a few functional C++ enhancements prior to moving onto
more advanced concepts.
