                  double xTolerance,
                  double fxTolerance)

Interface for testing for convergence in root finders.

Parameters:

xNow - Current root estimate.

xPrev - Previous root estimate.

fxNow - Function value at xNow.

xTolerance - Convergence tolerance for estimates.

fxTolerance - Convergence tolerance for function values.

Returns:

true if convergence achieved.
