Current behavior

Currently the documentation says to use type within the options params.

var options = {
  type: ['(regions)']
}

Expected behavior

The correct way to use the Google places API is by using types:

var options = {
  types: ['(regions)']
}

https://developers.google.com/places/supported_types

What is the motivation / use case for changing the behavior?

Saving time debugging :)

Environment

Angular version: 5.2
Angular Google place version : 0.0.3
