Each injector in an engine is a small rocket engine in it's self
optimize a single injector and you can use that to build an engine of
many injectors or enlarge the single injector to accommodate.
It's like cylinders in an IC engine. The first half of my life was
spent optimizing a single cylinder from here out we make it continuous
combustion that's pretty much the only difference I see in it.
That's a good thing to see an igniter open source because that is
actually the root of all evil.
