-* Add `make_tree()` function to build a tree from `Taxon` objects or a `LifeList`
-* Add `pprint_tree()` function to print a taxon tree on the console

 * Add `Observation.ident_taxon_ids` dynamic property to get all identification taxon IDs (with ancestors)
 * Add `Observation.cumulative_ids` dynamic property to calculate agreements/total community identifications
