/*
* After reconsidering how everything works, I've decided to make use of
* one large static dictionary to store info of alight+board for each bus UID.
*
* Previously it was found that simply reading the vehicle info is not enough to
* determine alight+board count because alighting uses another variable.
* Eventually I made use of two Harmony patches to read the alight+board info
* and write it to the static dictionary.
*
* The logic is now sth like this:
*
* When bus arrives at stop:
* Write down alighting+boarding count
* Determine if the bus can leave now given the alighting, boarding, and n-th stop info
*
* It is also determined that storing stop UID is not necessary because
* each bus can only stop at one stop at any given point in time.
* Stopping at a new stop will simply invalidate the previous stop info.
*
* This entire system has a nice property that no save-file access is needed.
