       | I've often wondered what the most optimal elevator algorithm is.
       | Imagine a scenario where a single person calls an elevator to go
       | down, and just as they get in, a group of five people on the
       | floor above also call the elevator to go down. We all know that
       | the elevator would go straight down and then come back up for the
       | people who called the elevator too late.
       | 
       | The elevator could actually save more time by letting the person
       | on the lower floor board, going one floor up, and letting the
       | group board before going back down. The algorithm could factor in
       | the number of people waiting on each floor, the time taken to
       | travel between floors, and how many people are already on the
       | elevator into account to optimise its route.
       | 
       | With multiple elevator shafts there's even more things to think
       | about. Could one shaft serve a lower set of floors while another
       | shaft serves a higher set of floors to minimise 'wasted' time
       | travelling up and down? Could the algorithm take into account the
       | time of day and the ingress/egress of people from the building?
