==============

A program to calculate effective interest rate (EIR) from given present value and a series of cash flow. 

It's similar to IRR function in Microsoft Excel.

Given the present value and a series of cash flow, we can transform them into a polynomial function. 

The root of this function is calculated using Newton-Raphson method and then will be used to find the EIR.
