Holds feature edges/points of surface.
Feature edges are stored in one list and sorted: 0 .. externalStart_-1 : region edges externalStart_ .. internalStart_-1 : external edges internalStart_ .. size-1 : internal edges
NOTE: angle is included angle, not feature angle and is in degrees. The included angle is the smallest angle between two planes. For coplanar faces it is 180, for straight angles it is 90. To pick up straight edges only use included angle of 91 degrees
