// <synopsis>
// TBTableTabs keeps track of the underlying TBTable object as well as the
// three tabs associated with its view (data, table keywords, and field
// keywords).  It is the unifying interface over the GUI and non-GUI aspects
// of a table.  Methods called on a TBTableTabs object tend to update the
// backend via the TBTable and then update the GUIs with the new data.
