I actually didn't realize until today that \"Mutual\" in StoredGraphDir meant undirected and was starting to write my own UndirectedGraph wrapper class when I noticed it.  How should we make this more clear?  For example I could add a comment to StoredGraphDir along the lines of\r\n`Mutual, // In a mutual graph, the outbound and inbound neighbors of each node are equal, and space is typically saved by only storing the outbound neighbors of each node`\r\nand/or add to the documentation of DirectedGraph that it actually also supports undirected graphs.  Or should there be an UndirectedGraph wrapper in Cassovary?\r\n@pankajgupta "}}
