reesporte 4c53f86e82 removed license from each go file
i used this script, a little clunky but it got the job done

```bash
for file in `find . -type f -print | grep '\.go'`; do
    sed '1,/^\/\/ limitations under the License.$/d' $file > $file.tmp;
    result=`cat $file.tmp`
    if [[ result != "" ]]; then
        gofmt $file.tmp &> /dev/null;
        if [[ $? == 0 ]]; then
            mv $file.tmp $file && gofmt -w $file;
        else
            rm $file.tmp;
        fi
    else
        rm $file.tmp;
    fi
done
```
