/* Year 9 Science lab pages: the "Class results" step (science/lab_data.py,

 * Three parts: the class table (what each group measured), the form that
 * adds a row, and the steps for the spreadsheet, each beside a drawing of the
 * sheet. Colour is never the only cue: the chosen cell of a drawing is named
 * in the box above the grid, and a teacher-only column says so under the
