examples of TabTemplate

I see examples of TabTemplate in the design guide ([here](https://developer.android.com/static/training/cars/Android%20for%20Cars%20App%20Library%20design%20guidelines.pdf))

Can someone add some examples of this template to the car-samples project?

Start with the Android for Cars App Library design guidelines linked in the issue and inspect existing examples in the car-samples project to find where templates are demonstrated. Add examples showing TabTemplate usage, with completion measured by the requested examples being present in the project.
