rs_ws281x 0.2.0

Wrapper for ws281x library using bindgen to track upstream
Documentation
## Run a demo

As this is just a Go wrapper for the library you must clone this into your `$GOPATH` as you would any other Go program. 
Your path to the project should be:
```
  $GOPATH/src/github.com/jgraff/rpi_ws281x
```


As listed in the `ws2811.go` file ensure to copy `ws2811.h`, `rpihw.h`, and `pwm.h` in a GCC include path (e.g. `/usr/local/include`) and
`libws2811.a` in a GCC library path (e.g. `/usr/local/lib`).

To run the basic example run the following commands:
```
  cd golang/examples
  go build basic.go
  sudo ./basic
```

If everything worked you should see a basic color wipe for the first 16 LEDs on your strip.
