Add barabasi_albert_graph random graph functions #1007
Conversation
This commit adds new random graph functions to rustworkx and rustworkx-core to implement a random graph generator using the Barabási–Albert preferential attachment method. It takes an input graph (defaulting to a star graph) and then extends it to a given size.

Not exactly sure what this line is doing.

Option<T>.map()
is just syntactical sugar and this is the equivalent of
match initial_graph {
Some(graph) => Some(graph.graph),
None => None,
}
Basically the type for initial_graph
is Option<PyGraph>
but the rustworkx-core function needs Option<StablePyGraph>
so I'm using a map here to pass the inner .graph
attribute if initial graph is set.
