Renumber the chapters by pedagogy, not history Basics, looking, measuring and segmenting, annotating, and the special formats last: audio moves after the looking block, pose estimation and segmentation move up from the tail, and 360/ambiscape close the course.

Home now presents the chapters as a course in four sections and points to the documentation site for concepts and reference.
