-- These should be pretty straight forward.  You need to provide a local file 
-- name to download the feed to (feedName), the URL to fetch from, displayMode
-- can be either "podcaset" or "webpage", which tells the module how to handle
-- the story body.
-- pageTitle is the thing that shows at the top of the list view.

--
-- The variable "composer" is just a Lua table that is returned from the 
-- require("composer" above.  As such, I can freely add members/attributes/entries
-- to the table.  By using this technique, I can quickly pass data between 
-- composer scenes.  It's like making them global without the penalties of 
-- making them global.  There is one catch... Corona Labs could come along and 
-- add theor own "displayMode" member (or any of them) later and trump yours
-- but the risk is minmal.
