Minimize Path Bends?

[blueslurpee]

Hello, thanks a lot for the great library, much appreciated.
I am using the library to find the optimal path between nodes in an orthogonal network layout (i.e. on a grid).

I was wondering if there might be a simple way to extend the library in order to minimize path bends??
The literature on graph layout algorithms/pathfinding is immense, perhaps someone already has a good idea for an implementation.

If someone has an idea how this might be possible I'm happy to work with them to submit a PR.

Thanks
