        // @Syntax sidebar (add/remove/{set}) (title:<title>) (lines:<#>|...) (values:<line>|...) (start:<#>/{num_of_lines}) (increment:<#>/{-1}) (players:<player>|...) (per_player)
        // @Required 1
        // @Short Controls clientside-only sidebars.
        // @Group player
        //
        // @Description
        // This command was created as a simpler replacement for using the Scoreboard command to display
        // per-player sidebars. By using packets and dummies, it enables you to have non-flickering, fully
        // functional sidebars without wasting processing speed and memory on creating new Scoreboards for
        // every single player.
        //
        // Using this command, you can add, remove, or set lines on the scoreboard. The 'lines' parameter
        // is used to specify which line you want to set using 'values:' or remove. It can also be used to
        // add lines in between existing lines. To change multiple lines at once, simply use a list in both
        // the 'lines:' and 'values:' arguments and have each index correspond with the other.
        //
        // Setting the title of the sidebar is extremely simple, and can be done by using the 'title:'
        // parameter in any case where the action is 'set'.
        //
        // To control which score numbers are shown, use the 'start:' and 'increment:' arguments in any case
        // where the action is 'set'. 'Start' is the score where the first line will be shown with. The default
        // 'start' value is determined by how many items are specified in 'values:'. 'Increment' is the difference
        // between each score and the default is -1. Using the default values of these, the sidebar displays each
        // line in order with the score counting down from the total number of lines to 1.
        //
        // The per_player argument is also available, and helps to reduce the number of loops required for
        // updating multiple players' sidebars. When it is specified, all tags in the command will fill based
        // on each individual player in the players list. So, for example, you could have <player.name> on a
        // lines and it will show each player specified their name on that line.

        // argument and the "id" argument, you will completely remove all the objectives in a scoreboard,
