Modify Task

The Modify Task example demonstrates the following:

• How to build a plugin module for the VR-Forces Gui
• How to override existing task dialog functionality and replace with your own
• How to register a task dialog to override an existing task dialog

This example adds a new label to the dialog called "Modified By Example" to show how an existing dialog can be modified.
