Move parentage code out of the OutputModule base class

[wmtan]

This simple PR is a small first step on the road to a global::OutputModule for thread safety. The data in OutputModule containing parentage information is currently incompatible with a "global" thread safe module. Fortunately, this data and the corresponding functions are needed only by one output module, namely PoolOutputModule. This PR moves this information from the base class into the only derived class that needs it. The thread safety of the derived class will be addressed later.

The unit test error exists in the base IB and is not caused by this PR.
