ShowManager manages PiPresents' concurrent shows. It does not manage sub-shows or child-shows but has a bit of common code to initilise them
concurrent shows are always top level (level 0) shows:
They can be opened/closed by the start show(open only) or by 'open/close myshow' in the Show Control field of players, by time of day sceduler or by OSC
Two shows with the same show reference cannot be run concurrently as there is no way to reference an individual instance.
