This is a simple feng shui compass, or known as Luo Pan, for feng shui analysis use.
It is intended to expand this feng shui compass to have more reference to actual analysis use case in future. For example, when maps connection is made available, a map will be overlayed.
thanks to the great wiki about using compass via Qt mobility at http://wiki.forum.nokia.com/index.php/Turning_phone_into_magnetic_compass_using_Qt_mobility_project
for fast head start into doing a Luo Pan
