/**
 * The demonstration application for the TableModel Free design pattern.
 * This application shows how multiple tables can be simplified
 * greatly by using the TMF.  It allows for swapping in and out
 * of both TMF code and classical Table Model code, to allow
 * for a side by side comparison.  Both implementations behave
 * exactly the same, the only difference is the code to make it work.
 * <p>The application itself acts as an "Evil HR Director's"
 * personal tool - a table on the left provides potential new hires,
 * while the tables on the right present the personal and financial
 * information of current employees.  The "Hire" button hires
 * an employee from the pool and moves their information over to the
 * current employees tables.  The "Fire" button deletes the former
 * employees records from both current employees tables.
 * <p>The main function to examine here is the <code>setupTables()</code>
 * function, which sets up the comparison between the TMF and classical
 * Table Model design. 
 * <p>The goal is to show how the TMF can be used - not to provide
 * a well rounded bug-free application.  Thus you may find 
 * exceptions.
