        // @Author Morphan1
        // @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.

        // Lets you make players see a certain scoreboard and then a certain objective in that scoreboard.
        //
        // There are currently three slots where objectives can be displayed: in the sidebar on the right of
        // the screen, below player names and in the player list that shows up when you press Tab. The names
        // of these slots can be found here:
        // http://jd.bukkit.org/rb/apidocs/org/bukkit/scoreboard/DisplaySlot.html
        //
        // Every objective has several lines of scores. Technically, the lines track players, but fake player
        // names can be used by Denizen to let you call the lines anything you want.
        //
        // When using the sidebar as the display slot, all the scores set for an objective will be displayed
        // there, but you will need to put actual player names in the lines to be able to use the below_name
        // display slot (which displays each player's score underneath his/her name) and the player_list
        // display slot (which displays each player's score to the right of his/her name in the player list).
        //
        // If you do not specify a display slot, the sidebar will be used. You can also use "none" as the
        // display slot if you want to add a hidden objective without automatically making it get displayed.
        //
        // You can set scores manually, or you can use different Minecraft criteria that set and update the
        // scores automatically. A list of these criteria can be found here:
        // http://minecraft.gamepedia.com/Scoreboard#Objectives
        //
        // You can use the "remove" argument to remove different parts of scoreboards. The more arguments
        // you use with it, the more specific your removal will be. For example, if you only use the "remove"
        // argument and the "id" argument, you will completely remove all the objectives in a scoreboard,
        // but if you specify an objective as well, you will only delete that one objective from that
        // scoreboard, and if you also specify certain lines, you will only delete those specific lines from
        // that objective. Similarly, if you use the "remove" argument along with the "id" and "viewers"
        // arguments, you will only remove those viewers from the scoreboard, not the entire scoreboard.
