+/**
+ * The glodasearch widget is a UI widget (the #searchInput textbox) which is
+ * outside of the mailTabType's display panel, but acts as though it were within
+ * it..  This means we need to use a tab monitor so that we can appropriately
+ * update the contents of the textbox.
+ *
+ * Every time a tab is changed, we save the state of the text box and restore
+ *  its previous value for the tab we are switching to, as well as whether this
+ *  value is a change to the currently-used value (if it is a faceted search) tab.
+ *  The behaviour rationale for this is that the searchInput is like the
+ *  URL bar.  When you are on a glodaSearch tab, we need to show you your
+ *  current value, including any "uncommitted" (you haven't hit enter yet)
+ *  changes.
+ *
+ *  In addition, we want to disable the quick-search modes when a tab is
+ *  being displayed that lacks quick search abilities (but we'll leave the
+ *  faceted search as it's always available).
