You should probably coordinate TINs with Laura, no point in duplicating

Note the current v.surf.rst in 5.7 still needs the 'deviation' output
updated to use the 5.7 points mode. Currently devi= doesn't export
anything useful. Shouldn't be too much work but should teach you
something about the 5.7 vector API.
Not sure if the treefile and overfile work either(?).
