// Purpose: This file contains the class definition for CTestRelativeTotalNormDispIncr.
// A CTestRelativeTotalNormDispIncr object tests for convergence using the ratio of the 
// current norm to the total norm (the total norm since start was invoked) of the 
// solution vector of the LinearSOE object passed in the constructor
// and a tolerance, set in the constructor.
