/**
* A helper to delay execution of a task that is being requested often.
*
* Following the throttler, now imagine the mail man wants to optimize the number of
* trips proactively. The trip itself can be long, so he decides not to make the trip
* as soon as a letter is submitted. Instead he waits a while, in case more
* letters are submitted. After said waiting period, if no letters were submitted, he
* decides to make the trip. Imagine that N more letters were submitted after the first
* one, all within a short period of time between each other. Even though N+1
* submissions occurred, only 1 delivery was made.
*
* The delayer offers this behavior via the trigger() method, into which both the task
* to be executed and the waiting period (delay) must be passed in as arguments. Following
* the example:
*
* const delayer = new Delayer(WAITING_PERIOD);
* const letters = [];
*
* function letterReceived(l) {
* letters.push(l);
* delayer.trigger(() => { return makeTheTrip(); });
* }
