    func main() {
    	// get an instance of writer
    	writer := goterminal.New()

    	for i := 0; i < 100; i = i + 10 {
    		// add your text to writer's buffer
    		fmt.Fprintf(writer, "Downloading (%d/100) bytes...\n", i)
    		// write to terminal
    		writer.Print()
    		time.Sleep(time.Millisecond * 200)

    		// clear the text written by previous write, so that it can be re-written.
    		writer.Clear()
    	}

More on usage

• Create a Writer instance.
• Add your text to writer's buffer and call Print() to print text on Terminal. This can be called any number of times.
• Call Clear() to move the cursor to position where first Print() started so that it can be over-written.
• Reset() writer, so it clears its state for next Write.
