 In this component, all descendants of `<google-map>` needed access to a `getMap` method, in order to know which map to interact with. Unfortunately, using the `$parent` property didn't scale well to more deeply nested components. That's where dependency injection can be useful, using two new instance options: `provide` and `inject`.
