Function source_grid 

pub fn source_grid(
    attention: &Attention,
    tr: &Translator,
    lines: &[SourceLine],
) -> Grid

The sources’ own rows as Settings draws them (AttentionGrid.qml): each a row of the nine columns, its cells as set or as usual, each in a sentence; a cell set carries the grid’s dot. The values a source’s cell takes, in their own words: at once, at the gathered times, held, as usual.
