Polyhedral surface

[robertogiachetta]

A polyhedral surface is a contiguous collection of polygons, which share common boundary segments. For each pair of polygons that "touch", the common boundary shall be expressible as a finite collection of line strings. Each such Line string shall be part of the boundary of at most 2 polygon patches. A TIN (triangulated irregular network) is a polyhedral surface consisting only of Triangle patches.

Create the IPolyhedralSurface interface in the Core namespace, and implement the interface in the PolyhedralSurface class as a descendant of Geometry in the Geometries namespace with in-memory storage of data.
