Finding and Obtaining Advertisables

Beyond just adding and removing Advertiseables from the AdvertService one can also query the AdvertService to determine what Advertiseables it contains and then obtain the desired Advertiseables from the AdvertService. This is done by creating a Table containing meta-data describing the Advertiseables you wish to find, then querying the AdvertService with this meta-data. With this meta-data, one can do a find, to see what's behind the black curtain, then obtain these Advertiseables a simple, wax-on, wax-off procedure.
