docs: Document MdInput focus() method

Document the MdInput focus() method

[fxck]

I think really think this belongs to the docs, it's a workaround for a missing feature(autofocus)..

The #nameInput isn't necessary in this example because you're using @ViewChild with the class. I'd omit it so that people don't mistakenly get the impression that a @ViewChild name has to match some template variable name.

[feloy]

You're right, I used the ViewChild incorrectly. What I wanted to write was instead:
@ViewChild('nameInput') nameInput: MdInput;
to that this sample still works when multiple md-input are present in the template.
Do you agree?

[jelbourn]

Yep, that works too.
