// Description: This file contains the class definition for 
// PeriodicNewton. PeriodicNewton is a class which performs a Periodic 
// Newton-Raphson  solution algorithm in solving the equations.
// No member functions are declared as virtual as 
// it is not expected that this class will be subclassed.
