// This class really refers to a device level concept of a single tracking
// unit, that is, some collection (possibly one) of emitters and tracking
// systems with a collection of receivers or tracked devices. For instance,
// the intersense emitters and trackers, a whole flock of birds, the whole
// polhemus system, etc. The trackers themselves refer to the widgets whose
// position is actually tracked.
