Class: Condition

A named condition of a task: a modelled state, event type, or baseline that an analysis can contrast against another. Only what happened inside the paradigm -- the occasion the task was run on and the arm it was run under are Timepoints and Arms, and enter an analysis as levels of their own model terms, compared by Cells on the Effect.

      A rest or fixation period inside another paradigm is a Condition of that paradigm''s

      What a tested effect was measured against is not recorded here: a contrast against
      this condition gives it a `negative` cell, and a contrast against the unmodelled
