 * File: conditionTimedDedup.h

 * Author: Kevin M. Karol
 * Created: 1/24/18
 *
 * Description: Condition which deduplicates its sub conditions results
 * Once the subcondition returns true once, the deduper will return false
 * for the specified interval, and then return the sub conditions results again
 * This makes it easy to toggle states based on conditions without worrying about
 * throttling back and forth on a per-tick basis
