 *  Description:                                            *
 *  This program determines whether a given year is a leap  *
 *  year based on the rules of the Gregorian calendar.      *
 *                                                          *
 *                                                          *
 *  Usage:                                                  *
 *  Call the leap_year() function with a year as input, and *
 *  it will return true if the year is a leap year, or      *
 *  false if it is not.                                     *
 *                                                          *
 *                                                          *
 *  Notes:                                                  *
 *  This function checks for leap years based on the rules  *
 *  of divisibility by 4, 100, and 400.                     *
 *                                                          *
 *  Test runs code in its own main file                     *
 *                                                          *
