 * Calculates Modified internal rate of return. Syntax is MIRR(cash_flow_values, finance_rate, reinvest_rate)
 * <p>Returns the modified internal rate of return for a series of periodic cash flows. MIRR considers both the cost
 * of the investment and the interest received on reinvestment of cash.</p>
 * Values is an array or a reference to cells that contain numbers. These numbers represent a series of payments (negative values) and income (positive values) occurring at regular periods.
 * <ul>
 *     <li>Values must contain at least one positive value and one negative value to calculate the modified internal rate of return. Otherwise, MIRR returns the #DIV/0! error value.</li>
 *     <li>If an array or reference argument contains text, logical values, or empty cells, those values are ignored; however, cells with the value zero are included.</li>
 * </ul>
 * Finance_rate     is the interest rate you pay on the money used in the cash flows.
 * Reinvest_rate     is the interest rate you receive on the cash flows as you reinvest them.
