Major Description
At this point, SaveHandler doesn't provide a way to configure where the content is saved, other than a single directory path, which clearly lacks flexibility.
A common scenario is to crawl a site and configure where the content gets saved based on some particular logic, as opposed to having all content (which may be a lot) saved in one single directory.
For example, I may want to save
www.domain.com/category1/... into directory a category1 directory and
www.domain.com/category2/... into directory a category2 directory.
