> assume the process is 
> 1. poll a link from queue
> 2. fetch entity
> 3. parse entity
> 4. extract outlinks
> we provide a mechanism to intercept the process in every stage. e.g. a LinkFilter has
a  "public T polled(T link);" interface, any filter may reject or transform a Link polled
from the queue. similar logic applies to fetching, parsing, and extracting (outlink)
