Performs a number of queries on the database, in an attempt to find a
SeriesRef object that strongly matches the given book. A variety of
techniques are employed, including checking for matching issue numbers in
the prospective series, and image matching the cover of the prospective
issue in the prospective series. The user's search and filtering
preferences (in 'config') are also taken into account.
Returns None if no clear seroes identification could be made.
