0029606: [Regression vs 7.0] BRepClass3d_SolidClassifier classifies the point as IN while it is ON

Browse Source 
Simple treatment of some analytical cases when curve is parallel or belongs surface is added in curve - face/surface intersection algorithm
Treatment such cases is added in classifier algorithm
Test case added
