Fifty shades of cash flow discounting.

Currently implemented functions (loosely inspired by MS Excel, but vectorized):

-   **dcf** – Day Count Fraction

-   **irr** – Internal Rate of Return

-   **npv** – Net Present Value

-   **pmt** – Annuity Payment

-   **ipmt** – interest part of an Annuity Payment

-   **ppmt** – principal part of an Annuity Payment

With hopefully more to come, but not very actively developed at present.

Implemented with minimal dependencies, mostly in base R.
