Function File: [omesh,nodelist,elementlist] = msh3m_submesh(imesh,intrfc,sdl)

Extract the subdomain(s) in sdl from imesh.

The row vector intrfc contains the internal interface sides to be maintained (field mesh.e(5,:)). It can be empty.

Return the vectors nodelist and elementlist containing respectively the list of nodes and elements of the original mesh that are part of the selected subdomain(s).
