* There are some climb characteristics (name, desceription, whether or not matching is allowed, setter info, edges, whether it is listed).
* The UUID is how we link the specifc climb to the other tables.

* So we understand HOW the board works pretty well now. Let's summarize.
* - There are about 128k climbs, across 3 layouts -- the TB1, TB2 (Mirror) and TB2 (Spray).
* - There are about 147k statistcs for climbs. This includes multiple angles for each climb.
* - Some key features are the frames, the angle, and the layout_id (the latter determins the board, the former the actual climb on the board)
* - Some key features are the frames, the angle, and the layout_id (the latter determines the board, the former the actual climb on the board)
* - Hold positions are decoded via mapping placements to (x,y) coordinates (from the holes tables)
* - There are four hold types: start, middle, finish, foot. 498 holds on the TB2.
* - There are different hold sets (e.g., Wood/Plastic on TB2).
