Modify Task Example

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

This example changes the "Move To Waypoint" dialog so that it no longer has the "Movement Method" selection box in the lower section of the dialog.
