Responsive view and sidenav

[Misiu]

First of all thank You for building and sharing this demo app.
I'd like to ask for some modifications.
I'd like to see responsive layout, because right now app looks ugly on mobile phone.
Second thing is sidenav. Right now it is just a div, I really would like to see menu like in admin templates.
I'd like to contribute, but I'm just starting with angular 2 and still looking for good resources and best practices.
