/**
 * This demo creates a simple GUI with a text window and two buttons, to simulate
 * a simple speech recognition application.
 * 
 * Clicking on one button toggles its label between "Start Recording" and
 * "Stop Recording".  The other button is labelled "Clear", but it doesn't do anything.
**/


/**
 * Class for handling ActionEvents (i.e., button clicks) on the first button.
 * It merely toggles the buttons title between two strings.
