AEPrelaunchHook

Bases: PreLaunchHook

Launch arguments preparation.

Hook add python executable and script path to AE implementation before AE executable and add last workfile path to launch arguments.

Existence of last workfile is checked. If workfile does not exists tries to copy templated workfile from predefined path.
