Leap

Write a program that will take a year and report if it is a leap year.

The tricky thing here is that a leap year 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.

Notes

For a delightful, four minute explanation of the whole leap year phenomenon, go watch this youtube video.

Setup

Go through the setup instructions for JavaScript to install the necessary dependencies:

Making the Test Suite Pass

Execute the tests with:

$ jasmine-node .

In many test suites all but the first test have been skipped.

Once you get a test passing, you can unskip the next one by changing xit to it.
