in support of a larger wrapping project.

E.g. This is used in GTSAM where we have a main gtsam.i, but various smaller .i files
which are the submodules.
The benefit of this scheme is that it reduces compute and memory usage during compilation.

Args:
    source: Interface file which forms the submodule.
