I was browsing the Credit page and noticed that it lists a private module among the others. Two thoughts occurred:

1. maybe we should filter private submodules from the list. I noticed the _fiff submodule isn't there so maybe the filter just needs to be generalized.
2. Maybe this submodule with its reading function for filelike object could be added to the edf module since it already has content for edf and bdf reading functions are.
