Support configuration for sandbox + production?

[subimage]

Hello! Thank you for providing this wonderful SDK for go users. I'm curious if you would consider making it possible to pass an auth configuration to switch between production and sandbox environments for testing? On configuration.go:63 the value for the production service is hardcoded. Yet, in swagger.yaml:23 there seems to be the ability to switch based on environment.

If this is possible, could you please provide documentation on how to make that happen? If not possible, may I please file a feature request? Thank you!

Sorry, I found a way!

cfg.BasePath = "https://connect.squareupsandbox.com"
