+Leap
+Given a year, report if it is a leap year.
+
+The tricky thing here is that a leap year in the Gregorian calendar occurs:
+
+on every year that is evenly divisible by 4
+  except every year that is evenly divisible by 100
+    unless the year is also evenly divisible by 400
+For example, 1997 is not a leap year, but 1996 is. 1900 is not a leap year, but 2000 is.
+
+If your language provides a method in the standard library that does this look-up, pretend it doesn't exist and implement it yourself.
