 							<li>By being Comparable we can take a small lineage model for a task (e.g. proposed calculating of cell X in a future version of BIRD), and compare it to another lineage model (e.g. the lineage model for all processing of the current version of BIRD) and look at what (if anything) changed when trying to achieve that task. We can also use this to view our small lineage model in the context of a larger lineage model.</li>
