/**
* VerticalFlowLayout is similar to FlowLayout except it lays out components
* vertically. Extends FlowLayout becau it mimics much of the behavior of the
* FlowLayout class, except vertically. An additional feature is that you can
* specify a fill to edge flag, which caus the VerticalFlowLayout manager to
* resize all components to expand to the column width Warning: This caus
* problems when the main panel has less space that it needs and it ems to
* prohibit multi-column output. Additionally there is a vertical fill flag,
* which fills the last component to the remaining height of the container.
