I'll probably take a shot at building a class to hold one tree per object, and search for objects of a class (per https://stackoverflow.com/questions/5158830/identify-all-objects-of-given-clas-for-further-processing) to implement collections when necessary... It does seem like there might be niche out there for a resource for folks deciding how to structure their package given what they're trying to provide; i.e. should they construct a collection of functions, or class defs, or... Could well exist already, and I may just have missed it... Thanks, Allie
