quickUnitNormal Method
compute and normalize cross product among 3 points on the linestring.
- "any" 3 points are acceptable -- no test for positive overall sense.
- This is appropriate for polygon known to be convex.
- use points spread at index step n/3, hopefully avoiding colinear points.
- If that fails, try points 012
