A simple string class was developed to keep track of the
operations on a matrix. The matrix name is private member
of a matrix, but adequate access is given for modifying it
from matrix member class functions. Implementing strings as
a class avoids some of the overhead normally associated
with character arrays in C. The allocation and length
control is encapsulated in the string member functions. The
string class is loosely associated with the string classes
in Schildt [#!sh:c++!#].
