Subject: [PATCH] Hierarchical edge bundling improvements.

The input to the layout is now an array of edges to bundle, rather than nodes.
This eliminates the need for an `outgoing` accessor, since the links are passed
to the bundle layout directly.

The svg line generator now supports a beta (straightening; bundle strength)
parameter. I haven't decided if this is the right place or the right name for
it, but it seems like a reasonable starting point. I'm not happy with the cos &
sin needed to produce radial lines (both here and for the diagonal projection in
other examples), but I don't have a good alternative yet.

This commit also tries to make the construction of the links from the layout
nodes a bit easier to follow. The previous code was used another intermediate
representation, and I think it's cleaner to construct the default format
expected by the layouts. However, there's still a good chunk of code required to
massage the JSON format into a node hierarchy and array of dependencies, so I'd
like to find a way to simplify that, too.
