<b>Geometric Progression</b> hypothesis allows splitting edges into
segments with a length that changes in geometric progression (Lk =
-Lk-1 * d) starting from a given <b>Start Length</b> and <b>Common Ratio</b>.
+Lk-1 * d) starting from a given <b>Start Length</b> and with a given
+<b>Common Ratio</b>.
The splitting direction is defined by the orientation of the
underlying geometrical edge.
