00032 // Description: This file contains the class definition for DomainSolver.
00033 // DomainSolver is an abstract base class and thus no objects of it's type
00034 // can be instantiated. It has pure virtual functions which must be
00035 // implemented in it's derived classes.  Instances of DomainSolver are used
00036 // to solve a system of equations and to do static condensation operations on the
00037 // linear system of equations.
