So I want to write a package for Querying Astronomy data and I want to make extensive use of submodules to seperate different queryable services. An example is in the following code:

```julia
module AstronomyQuery
    module Simbad

        export query_identifier

        function query_identifier(identifier::String)

            println("Nothing Implemented")

            return identifier
        end

    end

end

```

Now I seem to be too dumb to actualy figure out how to import that function. For example in my tests folder. Can anyone help me how to import the submodule correctly?

```julia
using AstronomyQuery.Simbad: query_identifier

```

(or just `using AstronomyQuery.Simbad` since the function is exported).
