New structure: - src/io/io.jl: IO submodule definition and exports - src/io/aster_reader.jl: Code Aster .med reader (ready for HDF5 extension) Benefits: - Clean separation of I/O code - ABAQUS reader works with stdlib only - Ready for package extensions (HDF5, LightXML) - Easy to add new formats (VTK, Gmsh, etc.) The IO submodule exports abaqus_read_mesh() to main JuliaFEM namespace.
