+--- An extention of task and token to allow a single require to register and run functions bypassing all permissions
+--[[
+>>>> Usage
+    To use sudo you must register the allowed functions when the files are loaded, often this will just be giving access to
+    some functions within a module if you expect that some parts may be blocked by in game permissions or a custom system you have made
+
+    -- this will be blocked if the current player (from a command or gui) is not admin
+    local function make_admin(player)
+        player.admin = true 
+    end
+
+    -- here we give sudo access to the function under the name "make-admin"
+    Sudo.register('make-admin',make_admin)
+
+    -- this will allow us to bypass this by runing one tick later outside of any player scope
+    Sudo.run('make-admin',game.player)
+
+>>>> Functions
+    Sudo.register(name,callback) --- Registers a new callback under the given name, used to avoid desynces
+    Sudo.get(name) --- Gets the function that is registered under the given name
+    Sudo.run(name,...) --- Runs the function that is registered under the given name, you may supply any number of params as needed
