Go class: Hello example (with UT)

Go class: Hello example (with unit test)

This example builds on the perennial first program, "Hello, world!"

1. We have a function that given some names, generates the "Hello, ..." string (using "world" if no names are given)

   say.go

2. We have a unit test which checks 0, 1, and 2 or more names as inputs to the function

   say_test.go

3. We use this function together with the command line arguments (except the first, which is the program name) to produce a result

   cmd/hello.go

Running and testing

$ go run ./cmd
Hello, world!

$ go run ./cmd class
Hello, class!

$ go run ./cmd class world
Hello, class, world!

$ go test ./...
ok  	hello	0.103s
?   	hello/cmd	[no test files]
