Symbolic description of one row before it is materialised in the matrix: a left * (something) * right triple.
preRowType decides what preRowIndex points at: ReducerPreRow indexes either mGroebner (>= 0) or mInput (< 0, decoded as -preRowIndex - 1); OverlapPreRow is a freshly added overlap whose polynomial lives in the current cohort's mRows; PreviousReducerPreRow refers back into mPreviousRows. The Words left and right are the leading monomial decomposition needed to materialise the row.
