Server addresses in the example

[zhanxw]

In the BGT example, on my server, 0.0.0.0 does not work:

curl -s '0.0.0.0:8000' | less -S  # help
curl -s '0.0.0.0:8000/?a=(impact=="HIGH")&s=(population=="FIN")&f=(AC>0)'

I switched it to 127.0.0.1 and then the example worked.

Thanks for letting me know. I'll leave this issue open until I fix README.
