Travis CI build is failing.

Looks like the imports are missing from the main.go file.

I have checked on my forked repo and you can add

before_script:

• go get

I bumped the language version to v1.13.8 as well due to a failure in the 'go get' using the current set version of 1.6. I will submit a PR.

Alternatively, the Makefile can run 'go get' to get all dependencies, which is probably better as anyone working on the repository will get the required dependencies by running the Makefile.

PR #47 submitted.
