/**
 * This Test demonstrates the "Event Weights" feature. Each Event from the
 * Stream is assigned a weight of "0.1". So, only after 10 events or more have
 * accumulated will the Query run. The Query's schedule-time is very large
 * (almost infinite). Therefore, only a total Event weight of 1.0 or more can
 * fire the Query.
