The following quote from Anders Logg might help you, But if you want to
tag the boundary which is complicated then I suggest using MeshBuilder
but if it is easily defined by hand then it is better to define the
SubDomains in main.cpp.

quote from Anders:
"The boundary is specified either by a subclass of SubDomain (which
must overload inside()) or by a MeshFunction<uint> over the facets of
the boundary. The mesh function can be created either manually (but
then using SubDomain is probably easier) or it can be created using
the graphical front-end MeshBuilder which can be obtained by"
