GitHooks

As there are many checks on our continuous integration server it's easy to accidentally forget something on a minor commit that could fail the build. No-one likes to be the one to cause a build to fail so instead why not install these git hooks to help avoid the extra work 😃?

Make sure that your $GOPATH/bin is in your environment path or this may fail! You also need to have goimports, golint and gocyclo installed, you can do this using go get golang.org/x/tools/cmd/goimports golang.org/x/lint/golint github.com/fzipp/gocyclo.
