Display Google Maps

A separate View that displays the Google Map. Can be static for now, as long as it shows/tests the features we will be using later (markers, custom style, etc).

Locate the app's existing view structure and identify where a separate map view belongs. Start by checking the current iOS project setup for Google Maps support, then determine how markers and custom styling are represented. Done means a static Google Map view demonstrates the planned marker and styling features.
