// This packet meter module measures the packet flow that is passing through
// using one token bucket. The meter attaches a ~LabelsTag to each packet with
// either a green or red color depending on whether the token bucket contains the
// required number of tokens for the packet.
//
// By default, packets consume 1 token per byte.
