          ParseResult getParse(Content c)

      This method parses the given content and returns a map of <key, parse> pairs. `Parse` instances will be persisted under the given key.

      Note: Meta-redirects should be followed only when they are coming from the original URL. That is:
      Assume fetcher is in parsing mode and is currently processing foo.bar.com/redirect.html. If this url contains a meta redirect to another url, fetcher should only follow the redirect if the map contains an entry of the form <"foo.bar.com/redirect.html", `Parse` with a `ParseStatus` indicating the redirect>.

      Parameters:
        `c` - Content to be parsed
      Returns:
        a map containing <key, parse> pairs
