 * This GUI application displays a grid that is used to train a Hopfield 
 * neural network.  To make use of this application draw small localized 
 * patterns on the grid and click train once each pattern has been drawn.  
 * The grid can be cleared between patterns.  Each pattern should be 
 * trained.  TO test, draw part of one of the patterns and select "GO".
