# function update (): polls for updates on one or more Contributor feeds
#
# Arguments:
# ----------
# * $uri (string): either the URI of the feed to poll, the URI of the
# (human-readable) website whose feed you want to poll, or NULL.
#
# If $uri is NULL, then FeedWordPress will poll any feeds that are
# ready for polling. It will not poll feeds that are marked as
# "Invisible" Links (signifying that the subscription has been
# de-activated), or feeds that are not yet stale according to their
# TTL setting (which is either set in the feed, or else set
# randomly within a window of 30 minutes - 2 hours).
#
# Returns:
# --------
# * Normally returns an associative array, with 'new' => the number
# of new posts added during the update, and 'updated' => the number
# of old posts that were updated during the update. If both numbers
# are zero, there was no change since the last poll on that URI.
#
# * Returns NULL if URI it was passed was not a URI that this
# installation of FeedWordPress syndicates.
#
# Effects:
# --------
# * One or more feeds are polled for updates
#
# * If the feed Link does not have a hardcoded name set, its Link
# Name is synchronized with the feed's title element
#
# * If the feed Link does not have a hardcoded URI set, its Link URI
# is synchronized with the feed's human-readable link element
#
# * If the feed Link does not have a hardcoded description set, its
# Link Description is synchronized with the feed's description,
# tagline, or subtitle element.
#
# * The time of polling is recorded in the feed's settings, and the
# TTL (time until the feed is next available for polling) is set
# either from the feed (if it is supplied in the ttl or syndication
# module elements) or else from a randomly-generated time window
# (between 30 minutes and 2 hours).
#
# * New posts from the polled feed are added to the WordPress store.
#
# * Updates to existing posts since the last poll are mirrored in the
# WordPress store.
