 The utility library contains Swift-friendly extensions of the [GMSGeometryUtils](https://developers.google.com/maps/documentation/ios-sdk/reference/group___geometry_utils) module of the Maps SDK for iOS. Rather than using C-Style functions in `GMSGeometryUtils`, you can use the Swift classes and extensions defined in this library.
