---------
Cooldowns
---------
You can set cooldowns for your custom commands. If a command is on cooldown, it will not be triggered.
You can set cooldowns per member or per channel, or set a cooldown guild-wide. You can also set multiple types of cooldown on a single custom command. All cooldowns must pass before the command will trigger.
