Description
This is a simple tag that allows any tag to be run asyncronously. It support's ctypes via the -owner property (providing the ctype is still "active"). Allows for modification of referenced variables and full logging via log_critical.
Sample Usage
Async: -tag = \include_url,
-params = array('http://www.google.com',
-nodata),
-log;

local:'result' = #tag->run(-params=#params,-owner=#owner);
// log result if -log specified
local_defined('log') ? log_critical:#tag' - '#result;
// set result if -set @var supplied
// useful for triggering simultaneous async events
local_defined('set') ? #set = @#result;
