Collections: Paleontology

[aazaff]

The new payload for collections is largely described in #35, but there are some objects that need to be resolved.

One object grouping is intended to be called "paleontology". It will likely contain some migration of information from the following fields, either verbatim or modified in some way.

1. pres_mode
2. taxonomy_comments
3. articulated_parts // likely discard
4. associated_parts // likely discard
5. disassoc_minor_elems // likely discard
6. disassoc_maj_elems // likely discard
7. art_whole_bodies // likely discard
8. disart_assoc_maj_elements // likely discard
9. common_body_parts // likely discard
10. rare_body_parts // likely discard
11. feed_pred_traces // likely discard
12. temporal_resolution
13. spatial_resolution
14. lagerstatten
15. concentration
16. preservation_quality
17. abund_in_sediment
18. sorting
19. fragmentation
20. collection_coverage
