Create stub for estimate_translations_walking.R tool.
Fork filter_delta_z.pl into filter_delta_z0.pl (like original), and new filter_delta_z.pl, operating on centroid delta Z.
Reduce layer tolerance to 25 um in plot_layer_translations.pl.
Create tool reformat_yml.py, in case we need it.
Enhance stitch_pair_fiji.py to filter neighbor tiles by delta Z range.
Enhance update_transforms.R to warn to stdout when tile rotations are larger than 0.5 radians.
