> - the main argument is, "fetcher" is a common terminology in crawling
> - a fetcher seems to be only required by droids-crawler but not in core.
> - this task is more about the creation of an interface and a concept. fetching function
exists already in HttpProtocol. 
> the fetcher shall have a "fetch()" method. I propose the following 2 main interface.
let it be evolved over time
>     public Fetcher<T> fetch(T link) throws FetcherException;
>     public Fetcher<T> fetch(T link, Map params) throws FetcherException;
