Description
Add a way to indicate that a primitive does not need to be applied to the whole input, but only to a part of it.
The selection of which columns to apply the primitive to should be done by either column name or index, and it should be possible to pass the selection in the live variables, allowing the implementation of detector primitives that do the selection in a previous step.

Research direction
Start by tracing how primitives receive their full input and how live variables are passed through the pipeline. Done means a primitive can be applied only to columns selected by name or index, with that selection supplied through live variables for detector-driven selection.
