Class to implement internal excel function RATE

Hi all.
It would be great to implement the internal financial excel function RATE. The
class in attachement is my own implementation but the most important thing is
the method calculateRate(double nper, double pmt, double pv, double fv, double
type, double guess) that find root by using the Newton secant method.
In this way it'd be possible to easily adapt the code.
I hope this will help the project with my few rows of code.
Feel free to contact me for any detail.
Regards,
Carlo Traversa.
