Move root experiment scripts into their papers' experiments/ folders

Browse Source 
Relocate the standalone Python scripts from the repo root into the
experiments/ folder of the paper each one belongs to:

  plane_depth_sequencing/experiments/
    plane_depth_sequencing.py, draw_quad_sequence.py,
    draw_quad_sequence_diagram.py, extract_sequence.py,
    plane_depth_sequencing_figure.py, quad_sequence_coloring_check.py
  colored_edge_flip_classes/experiments/   colored_edge_flip_class_survey.py
  colored_pentagon_contractions/experiments/ colored_pentagon_contractions.py
  plane_diamond_coloring/experiments/       plane_diamond_coloring.py

Each file that imports lib.* (still in the repo root) or the sibling
plane_depth_sequencing module gets a sys.path shim that prepends the
repo root (computed three levels up) and, where needed, its own dir.
Imports verified to resolve from a neutral working directory.

flip_symmetric_census.py is intentionally left in the root.
