CAUTION: Threshold depends on absolute value of x

int FindRoot(double &x, A &c)

virtual double dfdx(double x, A &)

Functions to be redefined when derive thiese classes for real use. If they are not derived, return 0

int FindNextRoot(double &x, A &c)

double gamma

this function makes one estimation. Returns 0 if OK, 1 if df/dx=0.0

double epsilon

damping factor (<=1. if =1, no damping)

int NIterMax
