*13.15 (Use BigInteger for the Rational class) Redesign and implement the Rational class in Listing 13.13 using BigInteger for the numerator and denominator.
*13.16 (Create a rational-number calculator) Write a program similar to Listing 7.9, Calculator.java. Instead of using integers, use rationals, as shown in Figure 13.10a. You will need to use the split method in the String class, introduced in Section 10.10.3, Replacing and Splitting Strings, to retrieve the numerator string and denominator string, and convert strings into integers using the Integer.parseInt method.
