This library allows you obtain the distance and travel times between multiple origins and destinations via various travel methods. The library handles Google API rate limiting and max encoded url length for you so you can just implement and enjoy :D
Limitations found here https://developers.google.com/maps/documentation/distancematrix/#Limits
Full details of the Google Matrix API is here https://developers.google.com/maps/documentation/distancematrix

- The library only implements origins and destinations in a coordinate format
- Currently only supports Driving, Walking and Bicycling travel modes
