◆ TriangleMeshPolygon()

		const Vector< double > &	internal_point_pt = `Vector<double>(0)`,
		const bool &	is_internal_point_fixed = `false`
	)

Constructor: Specify vector of pointers to TriangleMeshCurveSection that define the boundary of the segments of the polygon. Each TriangleMeshCurveSection has its own boundary ID and can contain multiple (straight-line) segments. For consistency across the various uses of this class, we insist that the closed boundary is represented by at least two separate TriangleMeshCurveSection whose joint vertices must be specified in both. (This is to allow the setup of unique boundary coordinate(s) around the polygon.) This may seem slightly annoying in cases where a polygon really only represents a single boundary, but... Note: The specified vector of pointers must consist of only TriangleMeshPolyLine elements. There is a checking on the PARANOID mode for this constraint.
