## Comments:
## Is dynamics_has_demolished_buildings = TRUE sufficient to prevent buildings being loaded? - No
## Lets mark them, then see if there even are any - would want to check for entire London
## Describe these changes in PR and ask for comment if the bool is sufficient

## Prerequisites:
## - Make geometries table have coordinates (load_coordinates.sh) - DONE
## - <mastermap download>= release_geometries
