===================================================================
Perform PAGA (partition-based graph abstraction) (`scanpy.tl.paga`)
===================================================================

Infer trajectories by mapping out the coarse-grained connectivity structures of
complex manifolds of single cell KNN graphs (Wolf et al, 2019).

This requires to run `Scanpy FindCluster`, first.

It yields `paga`, connectivity graph between clusters.
