//// COOLDOWN SYSTEMS
/*
 * We have 2 cooldown systems: timer cooldowns (divided between stoppable and regular) and world.time cooldowns.
 *
 * When to use each?
 *
 * * Adding a commonly-checked cooldown, like on a subsystem to check for processing
 * * * Use the world.time ones, as they are cheaper.
 *
 * * Adding a rarely-used one for special situations, such as giving an uncommon item a cooldown on a target.
 * * * Timer cooldown, as adding a new variable on each mob to track the cooldown of said uncommon item is going too far.
 *
 * * Triggering events at the end of a cooldown.
 * * * Timer cooldown, registering to its signal.
 *
 * * Being able to check how long left for the cooldown to end.
 * * * Either world.time or stoppable timer cooldowns, depending on the other factors. Regular timer cooldowns do not support this.
 *
 * * Being able to stop the timer before it ends.
 * * * Either world.time or stoppable timer cooldowns, depending on the other factors. Regular timer cooldowns do not support this.

/*
 * Cooldown system based on an datum-level associative lazylist using timers.

 * Stoppable timer cooldowns.
 * Use indexes the same as the regular tiemr cooldowns.
 * They make use of the TIMER_COOLDOWN_CHECK() and TIMER_COOLDOWN_END() macros the same, just not the TIMER_COOLDOWN_START() one.
 * A bit more expensive than the regular timers, but can be reset before they end and the time left can be checked.
