> Generator should support Jexl expressions. This would make it much easier to
> implement focussing crawlers that rely on information stored in the CrawlDB.
> With the HostDB it is possible to restrict the generator to select only
> interesting records but it is very cumbersome and involves
> domainblacklist-urlfiltering.
> With Jexl support, it is no hassle!
