AnalysisStepInput class

An individual analysis computation step. Where a step reads its data from, when that is another step's result rather than the spec's input sources.

Steps used to be siblings: every one of them ran over the same dataset and none could see what another produced, so a spectrum could be computed and then not be the thing the next step looked at. This is the output binding turned around — an output names the step field it carries, a step names the field it consumes.
