Delete .vscode/settings.json Publish shrinkGeometry. Refactor StdMeshers_Cartesian_3D and StdMeshers_Cartesian_VL classes to allow passing an arbitrary shrink mesh to the viscous layer builder. Use StdMeshers_Cartesian_VL in StdMeshers_ViscousLayerBuilder to handle geometry shrinking and viscous layer building. Create maps to link shrink solid and the solid assign to the shrink mesh. Code cleanup. Defining map btw original shape (TopAbs_COMPOUND) and result shrink object. Refactor to support viscous layer of faces. Code clean up and add of tests. Documentation and code cleanup erase debug comment. Modif after code review. Avoid compilation warning from ViscousLayerBuilder and ViscousLayerBuilder_i classes.
