Delivery Scheduling in City

Modified a concurrent scheduler approach to consider different priorities of tasks, and a practical counter to rotate use of resources for continuous performance analytics to minimize resources. 

Concurrent scheduler approach makes more sense compared to the usual Operations Research approach to scheduling/routing, as this approach is more dynamic, takes conservative traffic prediction into account but is responsive to current traffic condition, and promotes continuous improvement.

What is most important, is it is easy for a user to understand to improve continuously.
