	<possibleInterface>f(d) --> fast changing d</possibleInterface>
	hard coded and/or evolved
	Lambda, stateless
		many inputs and outputs (to be cycled together) for keeping state outside the lambda.
	All inputs and outputs are floating point, and the input and output float array are the same array
	so must always be the same quantity of floating points in and out.
