Proposed Change

Add a utility to take the output of a matching/error computation (annotated graphs), filter to subgraphs with error annotations, build small "matched" graphs (including the matching edges), and export those as graphml files. These can then be plotted with our docs example plotting function, if you sum all the spatial dimensions for the y axis.

Not sure how much of my use-case-specific setup leaked into here, since I basically just ported it over without the loading. But it's super useful already!! I had to resolve annotation discrepancies in two versions of annotations of the same tracks, and this narrowed it down to exactly the cases an annotator needed to resolve much better than individual lists of nodes/edges.
