This is a test of positional audio using SoundControl. All code added in
main is for the test. The ninja model will rotate around in the world and
the user can fly up to it and hear a positional ocean sound that follows
the ninja. The model/sound I used comes from the jme3-test library so one
must add this to the project in order for the test to work. Do this by
right clicking on the project->properties->libraries->add library->add the
jme3-test library.
Modified where the audio node is attached. It now attaches to the spatial
the SoundControl is attached to. This is done by casting the Spatial to a
Node, which is a sublcass of Spatial, to allow use of the addChild()
function. This may be dangerous and I need to research it more but it
works for now.
