// <--[command]
// @Name Light
// @Syntax light [<location>] [<#>/reset] (duration:<duration>)
// @Required 2
// @Maximum 3
// @Short Creates a light source at the location with a specified brightness.
// @Group world
//
// @Description
// This command can create and reset a light source at a specified location, regardless of the type
// of block. It will be shown to all players near the location until it is reset.
// The brightness must be between 0 and 15, inclusive.
// Optionally, specify the amount of time the light should exist before being removed.
// WARNING: May cause lag spikes, use carefully.
//
// Note that lights do not persist across server restarts, but will still be visible in the world
// after a restart until there is a block change near the location (to reset the light).
//
// @Tags
// <LocationTag.light>
// <LocationTag.light.blocks>
//
// @Usage
// Use to create a bright light at a noted location.
// - light MyFancyLightOfWool 15
//
// @Usage
// Use to reset the brightness of the location to its original state.
// - light MyFancyLightOfWool reset
// -->
