<h2>Adaptive hypothesis</h2>
<b>Adaptive</b> hypothesis allows to split edges into segments with a
length that depends on curvature of edges and faces and is limited
from up and down. In addition length of a segment depends on lengths
of adjacent segments (that can't differ more than twice) and on
distance to close geometrical entities (edges and faces) to avoid
creation of narrow 2D elements.
\image html adaptive1d.png
<b>Min size</b> parameter limits minimal segment size. <b>Max size</b>
parameter defines length of segments on stright edges. \b Deflection
parameter gives maximal distance of a segment from a curved edge.
