                          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.
