Nit picking

Hey,

kudos for sticking with `http.Handler`, the package looks really nice!

I just found a couple of small thing I would change. Mainly not ignoring the rrors from `cookieStore.Get`. It's not a problem because the session map lookup would fail anyway but If you really don't want to show that error you should log it at least, I think.

The rest is just styling. And.. The way you set up the templating, it would parse them on each request. It's just an example but don't do that :)
