//                          non-template classes CoolMatrix=>CoolBase_Matrix
//
// 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  protected 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 protected methods that are called by  the parameterized class to
// handle exceptions.
