Main lib returns object, not path string

[mhkeller]

The docs should be updated to reflect that require('app-root-path') returns an object, not the path string. It should be .require('app-root-path').path.

You actually don't have to use .path because the object provides a toString() method. So if you use the object like a string, it will behave like a string.

That said, it might not hurt to document that quirk.

The README.md has been updated. Thanks!
