    // @Name Command Syntax
    // @Description
    // Almost every Denizen command and requirement has arguments after the command itself.
    // These arguments are just snippets of text showing what exactly the command should do,
    // like what the chat command should say, or where the look command should point.
    // But how do you know what to put in the arguments?
    //
    // You merely need to look at the command's usage/syntax info.
    // Let's take for example:
    // - animatechest [<location>] ({open}/close) (sound:{true}/false)
    // Obviously, the command is 'animatechest'... but what does the rest of it mean?
    //
    // Anything in [brackets] is required... you MUST put it there.
    // Anything in (parenthesis) is optional... you only need to put it there if you want to
    // Anything in {braces} is default... the command will just assume this if no argument is actually typed.
    // Anything in <> is non-literal... you must change what is inside of it
    // Anything outside of <> is literal... you must put it exactly as-is
    // <#> represents a number without a decimal, and <#.#> represents a number with a decimal
    //
    // A few examples:
    // [<location>] is required and non-literal... you might fill it with '1,2,3,world' which is a valid location object.
    // (sound:{true}/false) is optional and has a default value of true... you can put sound:false to prevent sound, or leave it blank to allow sound.
    // (repeats:<#>) is optional, has no clear default, and is a number. You can put repeats:3 to repeat three times, or leave it blank to not repeat.
    // Note: Optional arguments without a default usually have a secret default... EG, the (repeats:<#>) above has a secret default of '0'.
    //
    // Also, you should never directly type in [], (), {}, or <> even though they are in the syntax info.
    // The only exception is in a replaceable tag (EG: <npc.has_trait[<traitname>]> will take <npc.has_trait[mytrait]> as a valid actual usage)
    //

        // @Author aufdemrand

        // @Description
        // Definitions are queue-level (or script-level) 'variables' that can be used throughout a script, once
        // defined, by using %'s around the definition id/name. Definitions are only valid on the current queue and are
        // not transferred to any new queues constructed within the script, such as a 'run' command, without explicitly
        // specifying to do so.
        //
        // Definitions are lighter and faster than creating a temporary flag, but unlike flags, are only a single entry,
        // that is, you can't add or remove from the definition, but you can re-create it if you wish to specify a new
        // value. Definitions are also automatically destroyed when the queue is completed, so there is no worry for
        // leaving unused data hanging around.
        //
        // Definitions are also resolved before replaceable tags, meaning you can use them within tags, even as an
        // attribute. ie. <%player%.name>

        // @Tags
        // %id% to get the value assigned to an ID

        // @Usage
        // Use to make complex tags look less complex, and scripts more readable.
        // - narrate 'You invoke your power of notice...'
        // - define range '<player.flag[range_level].mul[3]>'

        // - narrate '[NOTICE] You have noticed <player.location.find.blocks[%blocks%].within[%range].size>
        // blocks in the area that may be of interest.'

        // @Usage
        // Use to keep the value of a replaceable tag that you might use many times within a single script. Definitions
        // can be faster and cleaner than reusing a replaceable tag over and over.
        // - define arg1 <c.args.get[1]>
        // - if %arg1% == hello narrate 'Hello!'

        // @Usage
