/*
 * Autolabor module for dfhack
 *
 * The idea behind this module is to constantly adjust labors so that the right dwarves
 * are assigned to new tasks. The key is that, for almost all labors, once a dwarf begins
 * a job it will finish that job even if the associated labor is removed. Thus the
 * strategy is to frequently decide, for each labor, which dwarves should possibly take
 * a new job for that labor if it comes in and which shouldn't, and then set the labors
 * appropriately. The updating should happen as often as can be reasonably done without
 * causing lag.
 *
 * The obvious thing to do is to just set each labor on a single idle dwarf who is best
 * suited to doing new jobs of that labor. This works in a way, but it leads to a lot
 * of idle dwarves since only one dwarf will be dispatched for each labor in an update
 * cycle, and dwarves that finish tasks will wait for the next update before being
 * dispatched. An improvement is to also set some labors on dwarves that are currently
 * doing a job, so that they will immediately take a new job when they finish. The
 * details of which dwarves should have labors set is mostly a heuristic.
 *
 * A complication to the above simple scheme is labors that have associated equipment.
 * Enabling/disabling these labors causes dwarves to change equipment, and disabling
 * them in the middle of a job may cause the job to be abandoned. Those labors
 * (mining, hunting, and woodcutting) need to be handled carefully to minimize churn.
