Google Maps API for Business Signed HTTPBuilder

https://gist.github.com/joemccall86/7459214

Makes it dead-simple to call Google Maps API URLs. Automatically adds the client and signature parameters to the request. This is meant as a drop-in replacement for HTTPBuilder. It's particularly useful for those who originally tested calling the Google Maps API with anonymous calls using vanilla HTTPBuilder, but now need to use their credentials.

I hope this helps someone!
