// Configure the head tracker. The NewDevice command binds a logical name
// (the 2nd argument) to an InputDevice implementation whose class name is
// specified in the 3rd argument. The InputDevice implementation for a head
// tracker must generate position and orientation data relative to a fixed
// frame of reference in the physical world, the "tracker base" of the Java
// 3D view model.
//
// The InputDevice is instantiated through introspection of the class name.
// Available InputDevice implementations are site-specific, so substitute
// the class name in a NewDevice command below with one that is available at
// the local site.
//
// Note that properties are used to configure an InputDevice instead of
// attributes. The details of an InputDevice implementation are not known to
// ConfiguredUniverse, so the property name is invoked as a method through
// introspection. The example properties below must be replaced with the ones
// needed, if any, by specific InputDevice implementations. All arguments
// following the method name are wrapped and passed to the specified method as
// an array of Objects.
//
// All property arguments following the method name are wrapped and passed to
// the specified method as an array of Objects. Strings "true" and "false"
// get wrapped into Boolean, and number strings get wrapped into Double.
// Construct such as (0.0 1.0 2.0) and ((0.0 1.0 2.0 0.5) (3.0 4.0 5.0 1.0)
// (6.0 7.0 8.0 0.0)) get converted to Point3d and Matrix4d respectively.
// Note that last row of a Matrix4d doesn't need to be specified; it is
// implicitly (0.0 0.0 0.0 1.0).
