* sizes along invisible vertical and horizontal grid lines. It
* is important to sketch the layout of the interface and decide
* on the grid before writing the layout code.
*
*
* Here we actually use
* our own subclass of GridBagLayout called StringGridBagLayout,
* which allows us to use strings to specify constraints, rather
* than having to create GridBagConstraints objects manually.
*
*
* We use the JLabel.setLabelFor() method to connect
* labels to what they are labeling. This allows mnemonics to work
* and assistive to technologies used by persons with disabilities
* to provide much more useful information to the user.
