Smoothing Filter
This component creates a union of EPCs that are discovered over the number of
specified n cycles. If an EPC was discovered in cycle < n, it is reported. If an EPC has
not been viewed in more than the last n cycles, it is not reported. This component is
necessary because the RFID readers do not report tags with 100% accuracy.
