#
# * index - shows a list of WikiPages grouped by page or date
# * new - not used
# * create - not used
# * show - will also show the form for creating a new wiki page
# * edit - used to edit an existing or new page
# * update - used to save a wiki page update to the database, including new pages
# * destroy - normal
#
# Other member and collection methods are also used
