/**
 * Quick info on how this mod works:
 *
 * It tracks how many ticks a building was idle within X seconds to compute
 * the usage percentage.
 *
 * Every tick the logic checks if the building is idle, if so, it increases aggregatedIdleTime.
 * Once X seconds are over, the aggregatedIdleTime is copied to computedUsage which
 * is displayed on screen via the UsageStatisticsSystem
