The Pegasus String C++ Class implements the CIM string type

The Pegasus String C++ Class implements the CIM string type.

This class is based on the general handle/representation pattern

defined for all the Pegasus objects. However, it differes from

most in that it implements "copy on assign" all of the others implement

"no copy on assign" semantics. The string class uses the Array class and

implements an array of characters.
