Constructor & Destructor Documentation

SurveyDet::SurveyDet	(	const AlignableSurface &	surface,
		const align::ErrorMatrix &	errors
	)

Set the surface and 9 survey points to find its position and rotation.

--------— ^ --------— | . | . | . | | | 4 | 3 | 2 | --------— | --------— | . | . | . | L | 5 | 0 | 1 | --------— | --------— | . | . | . | | | 6 | 7 | 8 | --------— v --------— <-— W -—>

The left sensor shows how the 9 points are chosen (W = width, L = length) The right sensor shows how the points are indexed. Also set the survey errors.
