/**
 * LeapExample
 * 
 * A leap year (in the Gregorian calendar) occurs:
 * In every year that is evenly divisible by 4.
 * Unless the year is evenly divisible by 100, in which case it's only a leap year if the year is also evenly divisible by 400.
 * Some examples: 
 * 1997 was not a leap year as it's not divisible by 4.
 * 1900 was not a leap year as it's not divisible by 400.
 * 2000 was a leap year!
