+    Determine whether a given year is a leap year.
+
+    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!
