/*
 * Author: PabstMirror
 * Allows multiple sources to not overwrite showHud command.
 * Bitwise AND Logic (a single false in a mask will make it false).
 *
 * Arguments:
 * 0: Source ID <STRING> (default: "")
 * 1: Show Hud Bool Array (8 to set, empty to remove) <ARRAY> (default: [])
 * - [hud, info, radar, compass, direction, menu, group, cursors]
 * - hud: Boolean - show scripted HUD (same as normal showHUD true/false)
 * - info: Boolean - show vehicle + soldier info (hides weapon info from the HUD as well)
 * - radar: Boolean - show vehicle radar
 * - compass: Boolean - show vehicle compass
 * - direction: Boolean - show tank direction indicator (not present in vanilla Arma 3)
 * - menu: Boolean - show commanding menu (hides HC related menus)
 * - group: Boolean - show group info bar (hides squad leader info bar)
 * - cursors: Boolean - show HUD weapon cursors (connected with scripted HUD)
 *
 * Return Value:
 * Resulting ShowHud Array <ARRAY>
 *
 * Example:
 * ["hideHud", [false, true, true, true, true, true, true, false]] call ace_common_fnc_showHud; //This is equivalent to the old showHud false
 * [] call ace_common_fnc_showHud; //sets `showHud` and returns the result array used
 *
 * Public: Yes
