See the Google Map developer's site for the latest policies regarding usage and limits. If you expect to exceed the free usage limits or need to track usage (for which you need a key) you must obtain a Google Map API key and set this property.

The Google Map API is requested once only, so the key for the first map in the webroutine is used.
