emv c2a25d522b 0030785: Mesh - protect BRepMesh_IncrementalMesh::Perform from raising exception
IMeshTools_ModelAlgo and IMeshTools_ModelBuilder have been changed to provide exception protected interfaces for performing the operations.
Protect single Edge/Face discretization methods from raising exceptions to skip broken Edges/Faces and allow mesh construction on the whole model.
