=============================================================
Compute a neighborhood graph of observations (`pp.neighbors`)
=============================================================

The neighbor search efficiency of this heavily relies on UMAP (McInnes et al, 2018),
which also provides a method for estimating connectivities of data points -
the connectivity of the manifold (`method=='umap'`). If `method=='Gaussian'`,
connectivities are computed according to Coifman et al (2005), in the adaption of
Haghverdi et al (2016).
