1. Algorithm of Restriction line processing has been improved in IntTools_FaceFace.cxx file. 2. Algorithm of checking, if Restriction line and Walking line are coincided has been improved in IntPatch_ImpPrmIntersection.cxx file. 3. Algorithm of extending check if starting point of Walking line is a tangent point has been added. Small correction of some test cases. Creation of test case for issue #0026699. Small correction of test case for issue CR26699
