/**
* Default class for handling external calls as an FO Tree is being built.
* "External calls" are processes that are not directly related to building
* the FO Tree, but that are convenient to do while the tree is being built.
* This allows the FO Tree to be built without any knowledge of its eventual
* use, but allows the flexibility of having some additional processing related
* to that eventual use take place in parallel with the FO Tree construction.
* The default behavior is that no external processing takes place. Subclasses
* should override individual methods as needed.
* TODO: this should probably be a true singleton
