================================================
Calculate Diffusion Pseudotime (`scanpy.tl.dpt`)
================================================

Calculate diffusion pseudotime from single cell KNN graphs.

This requires to run `Scanpy DiffusionMap` and `Scanpy FindCluster`, first.

It yields `dpt_pseudotime`, diffusion pseudotime as an attribute for each cell.
