Modeling Algorithms - add NULL check to BRepGProp_Face::Load()

Notes
(0077257) git (administrator) 2018-07-04 12:13	Branch CR29926 has been created by kgv. SHA-1: 451be43367813fa0e9e6945ef437d183f0cc10b5 Detailed log of new commits: Author: kgv Date: Wed Jul 4 12:09:50 2018 +0300 0029926: Modeling Algorithms - NULL dereference within GProp_GProps on Edge without 2D Curve Added NULL check to BRepGProp_Face::Load().

(0077258) kgv (developer) 2018-07-04 12:15 edited on: 2018-07-04 12:15	Patch CR29926 just adds NULL check. As has been discussed, it is proposed adding an interface to high-level tools computing shape properties, which will return the completeness of computed values (e.g. enumeration - Complete, Failed and Partial).

(0077272) git (administrator) 2018-07-04 17:54	Branch CR29926 has been updated forcibly by kgv. SHA-1: b1ca535ea743b5f3ec4d08942ba2d1529d04bcb7
