installs the command to $GOPATH/bin/cli
Executing the command from $GOPATH/bin/cli is ambiguous.
Ideally you'd be able to install the command as shamir or go-shamir command.

$ shamir --help
Usage:
shamir [command]
...
Or even more simply just put the main.go in the repository root.
$ go install github.com/kinvolk/go-shamir@latest
$ go-shamir --help
Usage:
go-shamir [command]
...
It seems that running tests sometimes produce a warning, which I guess could be fixed.
