+# The WikiController follows the Rails REST controller pattern but with
+# a few differences
+#
+# * 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
