Update documentation to use pipeline workflow as primary approach #288
Description
Summary
The new pipeline workflow (assign_age_groups() → weigh() → compute_matrix() → symmetrise()/split_matrix()/per_capita()) provides a cleaner, more modular approach to computing contact matrices.
The documentation (README and vignettes) should be updated to present this as the primary/recommended approach, with contact_matrix() mentioned as a convenience wrapper for simple cases or legacy compatibility.
Tasks
- Update README.md examples to showcase the pipeline workflow
- Update the vignette to use the pipeline approach as the main tutorial
- Add documentation explaining when to use the pipeline vs
contact_matrix()
