Bug, feature request, or proposal:

The documentation is not clear on how to change the date format

What is the expected behavior?

Have a better example on how to achieve it

What is the current behavior?

It says it's easy but it's not

What is the use-case or motivation for changing an existing behavior?

Use the date picker on every application in the world

Which versions of Angular, Material, OS, TypeScript, browsers are affected?

Material beta.8
Angular 4.2.4

I tried to change the format to "dd MM yyyy" or "dd MMMM yyyy" but without any success.

Stackoverflow Angular 2 Material 2 datepicker date format

This post shows an example (which is incredibly complex for what we want to achieve) but it's not working.
