Profiles with Thickened Edges

[andrewheumann]

BACKGROUND:

• in Thickened polylines #1013, we introduced the ThickenedPolyline class.
• To continue our support for "edges with thickness," we want to add optional edge thickness data to a profile, which can be used to compute offset geometry for that profile.

DESCRIPTION:

• Introduces an optional Profile.EdgeThickness property
• Introduces three new methods for computing geometry using edge thickness:
  • Profile.ThickenedInteriorProfile
  • Profile.ThickenedExteriorProfile
  • Profile.ThickenedEdgePolygons

TESTING:

• Several tests are added
  
• A test function built off this branch lets you explore the functionality interactively: https://hypar.io/workflows/545a386f-f839-4a37-8239-47d4788bfe75

REQUIRED:

• All changes are up to date in CHANGELOG.md.

        public Profile Transformed(Transform transform)

            return new Profile(this.Perimeter.TransformedPolygon(transform), this.Voids?.Select(v => v.TransformedPolygon(transform)).ToList() ?? new List<Polygon>(), this._edgeThickness, this.Name);

This method will create a Profile with id = "0000 -00..." I'm not sure if it's ok

the base class Element constructor always makes sure the Id is valid. I wrote a throwaway test to confirm that Profile.Transformed always gives back a profile with a new Id.
