    // @format
    // The identity format for cuboids is <world>,<x1>,<y1>,<z1>,<x2>,<y2>,<z2>
    // Multi-member cuboids can simply continue listing x,y,z pairs.
    // For example, 'cu@space,1,2,3,4,5,6'.
    //
    // @description
    // A CuboidTag represents a cuboidal region in the world.
    //
    // The word 'cuboid' means a less strict cube.
    // Basically: a "cuboid" is to a 3D "cube" what a "rectangle" is to a 2D "square".
    //
    // One 'cuboid' consists of two points: the low point and a high point.
    // a CuboidTag can contain as many cuboids within itself as needed (this allows forming more complex shapes from a single CuboidTag).
    //
    // Note that the coordinates used are inclusive, meaning that a CuboidTag always includes the blocks identified as the low and high corner points.
    // This means for example that a cuboid from "5,5,5" to "5,5,5" will contain one full block, and have a size of "1,1,1".
    //
    // This object type can be noted.
    //
    // This object type is flaggable when it is noted.
    // Flags on this object type will be stored in the notables.yml file.
    //
    // @Matchable
    // Refer to <@link objecttype areaobject>'s matchable list.
