Filter a VertexClustering object based on cluster sizes

> Would it make sense to add a helper function to the C core which can retrieve the IDs of edges contained within a subgraph induced by some vertices? Sounds...

"Unknown fields" in documentation

I've started cleaning this up in `develop`.

"Unknown fields" in documentation

Docs cleaned up.

write_graph() and read_graph should detect format from file name

Pajek is typically `.net`. Edgelist files can be pretty arbitrary; it is to be debated whether we should automatically attempt to parse `.txt` files as edgelist or not. NCOL and...

write_graph() and read_graph should detect format from file name

The site linked above for GML has a login prompt; I guess it's not available any more. So what's left for us is to take one of the "famous" graphs...

write_graph() and read_graph should detect format from file name

[celegansneural.zip](https://github.com/igraph/rigraph/files/10239480/celegansneural.zip) This is the C.elegans neural network from Mark Newman's page, converted into GML, GraphML and Pajek. This should be suitable for testing purposes.

write_graph() and read_graph should detect format from file name

[lesmis.zip](https://github.com/igraph/rigraph/files/10251501/lesmis.zip) This is the Les Miserables network in GML, GraphML and Pajek.

write_graph() and read_graph should detect format from file name

Overview documentation for current functions

Yes, sounds like a good idea.

Be able to read and write to strings in read_igraph, write_igraph

> don't understand the implementation of, e.g., R_igraph_write_graph_graphml() for the case HAVE_OPEN_MEMSTREAM == 1 . It seems to return a raw vector and never write to the file given by...
