-/**
- * 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
