gs-JSON is a domain agnostic unifying 3D file format for geometric and semantic modelling (hence the 'gs').

 * Class Polymesh.
 * A polymesh is defined by a set of polygonal faces.
 * These faces may have arbitrary number of vertices,
 * may be concave or convex, and may be planar or non-planar.
 * All faces are expected to be connected to one anoter, so that there are no disjoint parts.
 * The polymesh will have closed wires along all its naked edges.
 * The polymesh may include one or more holes.
 * The holes will result in additional naked edges, each with their own wire.
 * A polymesh may be part of a group and may have attributes.
