Are there hand-generated baselines for the test-files? In particular, I'm wondering if there are
A) CSV files generated from various versions of Excel
B) Manifest of the formulas in the sheet (written like "A3=A1+A2" or
"C1:C2{=A1:A2*B1*B2")
C) HTML renderings of the cells (like what Excel puts in the HTML
pasteboard)
