OBSOLETE GUIKIT PACKAGE TUTORIAL
The functionality provided by GUIKit has been superseded by the interface construction
functions native to the built-in Wolfram Language.
GUIKit Example: PlotGroup
This example demonstrates how to create a reusable GUIKit` widget for wrapping Plot and some of its options.
You can easily treat the PlotGroup example as a single reusable user interface element within other panels and even use multiple instances.
