=============================================================
Plot embeddings of a given method of dimensionality reduction
=============================================================

It yields a scatter plot in png format, wherein cells are placed in space of
reduced dimensionality and coloured by attribute of choice.

Requires calculating the specified embeddings first. For example, to make
UMAP/TSNE plots, run `Scanpy RunUMAP`/`Scanpy RunTSNE` first, then enter
"umap"/"tsne" as the name of the embedding to plot here.
