Perhaps agregation would be better than inheriting - some modules need to have
access to IO management, so putting that into a single place into a module is
sensible, but mabey the IO modules that use this functionality just need an
IOManager object as a member variable - and there is bound to be one case in
the future when an IO module needs more than one IOManager for something. Also,
there may be some specific case in the future when two objects need access to
the same IOManager resources. This would be problematic if they inherited this
functionality in rather than delegating it.
