| The project stack dimensions and resolution are used to inform the bounding box | ||
| of the data in neuroglancer as their product. Skeletons in CATMAID are in 1 nm | ||
| units. Optionally, you can also configure cache grid | ||
| metadata, which is intended to be used alongside the CATMAID multiple-LOD cache |

The stack metadata now it's not related with the cache as it was in the past.
{"cache_provider": "cached_msgpack_grid", "spatial_skeleton_chunk_sizes": [[12058882, 12058882, 12058882], [7161485, 7161485, 7161485], [4253037, 4253037, 4253037], [2525778, 2525778, 2525778], [1500000, 1500000, 1500000]]}
spatial_skeleton_chunk_sizes defines the chunk sizes to be made available by neuroglancer. It does not match 1 to 1 with the existent catmaid grid sizes (we removed the coarser grids to make the update of the cache easier)
cache_provider we probably should remove because cached_msgpack_grid is the only one we are comfortable using. Other options we tried were 'postgis3d' which hits the db directly but it's very slow and cached_json_grid which returns in json opposed to msgpack; msgpack in theory is faster.

- Make the node the root of the skeleton

There's this exceptional case where the surviving skeleton can be the 'to'. Currently it can't happen in our skeletons because we don't annotate them. But in general, a group that uses catmaid with annotations and wants to see their data in neuroglancer can experience that.

Will require a cleanup at some point, and links etc. Also still need to test the docs build.
