0028715: Invalid shape produced by reading of attached STEP file. Regression from OCCT-6.9.1 to OCCT-7.0.0.

Browse Source 
Corrections: to use fixed shape as result in the non-manifold mode was made.

Regression was due to using modified initial shape as result in the previous version OCCT. At present initial shape is not modified during ShapeProcessing. Therefore modification to use fixed result was made.

Additionally using of nonManifold flag is added to ShapeProcessing.
