Data for testing the registration algorithm

[gogojjh]

Very nice works!

Hi, authors, it is very interesting to formulate the registration problem using the distance field. The code provides an example to test the registration algorithm: registration_test_bench.cpp. It seems that the program takes multiple submaps as input (

voxgraph/voxgraph/config/registration_test_bench.yaml

Line 1 in bd802b5

submap_collection_file_path: "/home/victor/data/voxgraph/submap_collections/burning_house_rubble_gt_truncdist06_z-aligned"

). I wonder if you will release the submap data for the separate registration test?
I am looking forward to your reply.

Thanks.
