go does not pull in packages

# Does not work!
dep ensure -add github.com/gizak/termui

* The above fails:
could not find project Gopkg.toml, use dep init to initiate a manifest

* without doing the above, go does not fetch packages using /v3

## Apart from that
Apart from that the thing looks really great, except I cannot make it work!

## Go get <---------->
go get fails as it says there is no toml file

## Please let me know how to use this

**thanks**

The issue names no repository files or tests. Start by reproducing `dep ensure -add github.com/gizak/termui` and `go get`, then inspect the repository's dependency setup and `/v3` entry points to determine the supported workflow; done means dependencies can be fetched successfully using documented commands.
