/**
 * The TableModelExample uses the classical TableModel - what most GUI developers
 * use everyday - to model their tables.  Over 200 lines more than the TMF using TableModelFreeExample.
 * None of this code should look odd to any developer - it's standard TableModel
 * code, which now, after reading the TMF, seems far too lengthy and bloated.
