 * This class is for you to use
 * This class implements a Comparator for Integers. Two Integers are compared by
 * their numerical values, which follows classic intuition about integer
 * comparison. The first integer is considered less than the second integer if
 * its numerical value is less than the second integer's numerical value. The
 * first integer is considered greater than the second integer if its numerical
 * value is greater. Otherwise, the two are considered to be equal.
