------- Comment #3 from leinfelder at nceas.ucsb.edu  2008-01-04 12:12 -------
Added a recast() method to the PersistentTableModel implementation.  This
allows us to make an initial pass over the columns to divine the type correctly
(which in turn allows the cells to be rendered with right-justified numbers,
and left-justified strings and also to be sorted appropriately).
Note: Since there is an initial pass over _every_ cell in the table to divine
the type of the column, there could be some overhead when dealing with large
Note 2: "Missing values" are not really supported in that if a column of
numbers includes something like "-" or "N/A" for a missing value then the
entire column will be treated as a string (for display and sorting).
