    // @group Object System
    // @description
    // ObjectTags are a system put into place by Denizen that make working with things, or 'objects',
    // in Minecraft and Denizen easier. Many parts of scripts will require some kind of object as an
    // argument, identifier/type, or such as in world events, part of an event name. The ObjectTags notation
    // system helps both you and Denizen know what type of objects are being referenced and worked with.
    //
    // So when should you use ObjectTags? In arguments, event names, replaceable tags, configs, flags, and
    // more! If you're just a beginner, you've probably been using them without even realizing it!
    //
    // ObjectTag is a broader term for a 'type' of object that more specifically represents something,
    // such as a LocationTag or ScriptTag, often times just referred to as a 'location' or 'script'. Denizen
    // employs many object types that you should be familiar with. You'll notice that many times objects
    // are referenced with their 'ObjectTag notation' which is in the format of 'x@', the x being the specific
    // notation of an object type. Example: player objects use the p@ notation, and locations use l@.
    // This notation is automatically generated when directly displaying objects, or saving them into data files.
    // It should never be manually typed into a script.
    //
    // Let's take the tag system, for example. It uses the ObjectTags system pretty heavily. For instance,
    // every time you use <player.name> or <npc.id>, you're using a ObjectTag, which brings us to a simple
    // clarification: Why <player.name> and not <PlayerTag.name>? That's because Denizen allows Players,
    // NPCs and other 'in-context objects' to be linked to certain scripts. In short, <player> already
    // contains a reference to a specific player, such as the player that died in a world event 'on player dies'.
    // <PlayerTag.name> is instead the format for documentation, with "PlayerTag" simply indicating 'any player object here'.
    //
    // ObjectTags can be used to CREATE new instances of objects, too! Though not all types allow 'new'
    // objects to be created, many do, such as ItemTags. With the use of tags, it's easy to reference a specific
    // item, say -- an item in the Player's hand -- items are also able to use a constructor to make a new item,
    // and say, drop it in the world. Take the case of the command/usage '- drop diamond_ore'. The item object
    // used is a brand new diamond_ore, which is then dropped by the command to a location of your choice -- just
    // specify an additional location argument.
    //
    // There's a great deal more to learn about ObjectTags, so be sure to check out each object type for more
    // specific information. While all ObjectTags share some features, many contain goodies on top of that!
