Solution: Use window.location instead of bare location.

ServiceWorker for github pages

This is a ServiceWorker template to turn small github pages into offline ready app.

Why ?

Whenever I make small tools & toys, I create github repo and make a demo page using github pages (like this one).
Often these "apps" are just an index.html file with all the nessesary CSS and JavaScript in it (or maybe 2-3 html/css/js files). I wanted to cache these files so that I can access my tools offline as well.

Notes

Make sure your github pages have HTTPS enforced, you can check Settings > GitHub Pages > Enforce HTTPS of your repository.

	These are the solutions to all the "experiments" in the pre-release Swift Programming Guide
	(released on the same day Apple announced Swift). A couple of things worth noting:

	1. Swift syntax, e.g. array declarations, has changed since I releasd these. So this code will
	probably cause some errors when you paste it into a playground. Should be easy enough to fix
