add a Makefile?

[kevinburke]

The test tool people might be used to running (go test ./...) both iterates over the vendor directory and is slow (98 seconds on my machine).

maybe we could add some targets for e.g. make test, make race-test, make unit, make vet to tell people how to run the tests in various circumstances? Also could use those targets in the .travis.yml file.

hahha I tried this: #51

but to be honest the go team seems to be pretty against makefiles and running tests is as easy as go test w no args same goes for install and build so i dont really see an issue

OK

I use an uncommitted Makefile so that I don't forget key steps before submitting a PR. I may not be the only contributor who would appreciate a single command to validate their branch before making making preventable mistakes (like forgetting to run go fmt or adding a new test file without a license at the top).
