Mesh representation

[ly29]

To have two types SMesh and BMesh which are considered compatible and converted as needed by the system.
SMesh is an Sverchok representation of a mesh using flat numpy storage.

The two types would have the same socket representation but the mesh data would be converted as needed. Perhaps also allow overload for certain functions and have two functions to avoid conversion.

To the user and the nodes this would basically be invisible, the intelligence would be in the base system

So SvPolygon for flat storage of polygons. Backwards compatible to Sverchoks old format but new numpy storage which is similar to blenders loops.
