Detailed Description

Generic way to add edge connectivity iteration support to any mesh that looks like a TTriangleMeshAdapter The interface is designed to match a subset of the FDynamicMesh3 query methods Note that unlike FDynamicMesh3, it does support edge-non-manifold mesh topology (i.e. edges with more than 2 triangles)
