/**
 * <code>Tab</code> is the abstract superclass of every page
 * in the example's tab folder.  Each page in the tab folder
 * describes a control.
 *
 * A Tab itself is not a control but instead provides a
 * hierarchy with which to share code that is common to
 * every page in the folder.
 *
 * A typical page in a Tab contains a two column composite.
 * The left column contains the "Example" group.  The right
 * column contains "Control" group.  The "Control" group
 * contains controls that allow the user to interact with
 * the example control.  The "Control" group typically
 * contains a "Style", "Other" and "Size" group.  Subclasses
 * can override these defaults to augment a group or stop
 * a group from being created.
