Hello World

Commentary to main.go file

import imports packages

To run the program, use the command go run main.go while in ~/heraclea/golanggocode/src/github.com/saraginov/goByExample/001helloWorld

Sometimes we want to build our programs into binaries, we can do this using go build instead. We can then execute the built binary directly.

Note to self: I don't see an advantage of building binary yet, especially during development process...
