// The parameterized CoolMatrix<Type>  class is publicly   derived from the  CoolBase_Matrix
// class and implements two dimensional arithmetic matrices of a user specified
// type.   This is accompilshed by using  the parameterized  type capability of
// C++.  The only constraint placed on the type  is  that it must  overload the
// following operators: +, -,  *,  and /. Thus, it will  be possible to have  a
// matrix of  type Complex.  The CoolMatrix<Type> class  is static in size, that is
// once a  CoolMatrix<Type> of  a particular  size has been   declared, there is no
// dynamic growth or resize method available.
//
// The CoolBase_Matrix class is the base class for the parameterized  CoolMatrix<Type> class
// and implements all non-type specific functionality. The private data section
// contains two slots to maintain  the row  and column specification. There are
// two constructors  for  the CoolBase_Matrix  class. The   first   takes  two arguments
// specifying the number of rows and columns. The second takes a reference to a
// CoolBase_Matrix object and  reproduces its state. There  are  two public methods that
// provide accessors to the row  and column slots.  Finally, there are  several
// private  methods  that  are called   by the   parameterized class to  handle
// exceptions.
