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
