Group by folder

[goodmind]

Can it group files by parent folder in generated image?

Similar to #181 ?

I wrote a filter that does that:

@joebowbeer I mean with --image option

[joebowbeer]

@goodmind pipe the results through a transformer (such as mine) and then back into madge via the --stdin option:

madge --json app.js | repdeps -x '([^\/]*).*' -r '$1' | madge --stdin --image graph.svg

[goodmind]

@joebowbeer Yeah, similar to this, but actually show files in folder as subgraph

This would be very useful -- for projects larger than a dozen files the graph becomes unreadable, because the nodes are placed chaotically, so it's hard for a human to follow the links. Files in a folder are naturally grouped together, and it would greatly increase "at a glance" readability of the generated image.

For example, dependency-cruiser uses graphviz's clusters to do that, see examples here.
