How to update dependencies

[srossross]

First of all, Thank you! This is the missing demo I have been searching for. Great job.

How do I update/add to the vendor dependencies in this project? dep ensure updates the existing dependencies and cause the build to fail.

dep ensure is the correct way to update dependencies. Perhaps a note in the README would help here.

So long as the Gopkg.lock and Gopkg.toml are in sync, this should not cause any changes. Running dep ensure -update will update existing dependencies (potentially causing failures).
