> If an annotator creates an AE to run an independent pipeline with a different typesystem
it can't reuse the RM as the CasManager's merged typesystem cannot be updated.  We should
be able to create a child RM that shares the resources (delegates to the parent?) but has
a unique CasManager.  The 5-arg RM constructor used for pears can be used but it requires
access to maps that are protected in the existing RM.  Perhaps we could add:a method such
as: 
> ResourceManager createChild();
> Destoying a child RM should not affect the parent and vice-versa.
