 Utility to generate a polhedron by sweeping a 2D profile along a 3D path and utilities for generating paths.
 
 The initial orientation is the Y axis of the profile points towards the initial center of curvature, Frenet-Serret style.
-This means the first three points must not be colinear. Subsequent rotations use the minimum rotation method.
+Subsequent rotations use the minimum rotation method.
 
 The path can be open or closed. If closed sweep ensures that the start and end have the same rotation to line up.
 An additional twist around the path can be specified. If the path is closed this should be a multiple of 360.
