0030679: Attached model hangs most of OCCT common functionality

Browse Source 
Evaluator of offset surface has been protected against evaluation at infinite parameters. Now it throws exception when evaluating such data.

The methods IsUClosed and IsVClosed of the class ShapeAnalysis_Surface have been corrected to avoid evaluation of the surface at infinite parameters (fighting with regressions "parasolid doc_3 E3" and "parasolid doc_2 A3" in products).
