Interface Summary

Estimate	An Estimate is made by Trackers from Measurements.
EstimateListener	An EstimateListener can be registered with a Tracker to be notified when the Tracker updates.

Class Summary

BeaconAndGPSParticleFilterTracker	A Tracker for beacons and GPS that uses a probabilistic technique to produce Estimates.
BeaconTracker	This is the base class for all Beacon-based trackers.
BestGuessCompoundTracker	A CompoundTracker that simply returns whichever estimate has the lowest standard deviation.
CentroidTracker	A simple tracker that computes the geometric center of the current set of readings.
CompoundEstimate	CompoundEstimates are produced by CompoundTracker objects.
CompoundTracker	A CompoundTracker encapsulates multiple Tracker objects in a single Tracker.
FilteredEstimateListener	This filters estimateUpdated measurements by either count or time.
FixedTwoDPositionEstimate	An Estimate whose Coordinate is a FixedTwoDCoordinate.
HamsterTracker	A Tracker that wraps another Tracker and makes it behave like a Hamster in a ball.
IntersectionTracker	The IntersectionTracker performs basic "fusion" by taking both PositionMeasurements and BeaconMeasurements and creating Estimates that take both types into account.
ParticleFilterTracker	A Tracker that uses a probabilistic technique to produce Estimates.
ParticleTwoDEstimate
PositionTracker	A Tracker that takes PositionMeasurement objects and returns the latest measurement as its estimate of position.
SmoothingTracker	This simple smoother creates a reading that is a mix of the last 2 Estimates produced by a wrapped Tracker.
StationaryPositionTracker	A sample tracker that always returns the same position as its estimate
ThreeDPositionEstimate	An Estimate whose Coordinate is a ThreeDCoordinate
Tracker	A Tracker takes Measurement objects and then uses them to produce an Estimate.
TwoDPositionEstimate	An Estimate whose Coordinate is a TwoDCoordinate
