"Solid from faces" node

Слиты nikitronn запросил слияние solid_from_faces в master

Created by: portnov

This node takes several Solid Face objects (i.e. Surfaces trimmed by some edges), and "glues" them to construct a Solid object. In order to make a proper Solid object, the faces must already have their edges and vertices exactly coinciding. Usually the only way to guarantee that is to construct all these Faces from the same set of Edges.

Solid Face object can be created with nodes from "Make Face" submenu (such as "Face from Curve"); also any NURBS or NURBS-like surface can be used as a Solid Face.

NOTE: some operations with Solid objects which are not "valid" (in terms of FreeCAD's OCCT kernel) are known to cause crashes. So it is strongly recommended to have "Validate" parameter checked.
