"""
180530: Due to failures in senwIsoStatusIntersectingTrimPointAtStart, changed fRh0Tol (in all functions) from Rhino.RhinoMath.ZeroTolerance to 0.1 * sc.doc.ModelAbsoluteTolerance.
190413: Created by extracting functions from xBrep.  Renamed a function.
190513: Moved a couple of functions to only script that currently uses them.
