QR encoder in Go based on the ZXing encoder (http://code.google.com/p/zxing/).

I was surprised that I couldn't find a QR encoder in Go, especially

since the example at http://golang.org/doc/effective_go.html#web_server

is a QR code generator, though the QR encoding is done by an external

Google service in the example.

# Example

```go

package main

import (

	"bytes"

	"image/png"

	"os"

	"github.com/qpliu/qrencode-go/qrencode"

)

func main() {

	var buf bytes.Buffer

	for i, arg := range os.Args {

		if i > 1 {

			if err := buf.WriteByte(' '); err != nil {

				panic(err)

			}

		}

		if i > 0 {

			if _, err := buf.WriteString(arg); err != nil {

				panic(err)

			}

		}

	}

	grid, err := qrencode.Encode(buf.String(), qrencode.ECLevelQ)

	if err != nil {

		panic(err)

	}

	png.Encode(os.Stdout, grid.Image(8))

}

```
