What?

Introduces smart routing to the library.

Why?

For some use cases an automatically generated orthogonal representation of the links results in a better visualisation.
It also improves the overall aesthetic as links find their way around other nodes.

How?

Basically a combination of PathFinding.js and Paths.js, with extra bits of magic to put everything to work together. :)

Demos?

Yes, many!
There is a new storybook entry + demos for enabling it by default to confirm it works well with all other setups already handled by the library.
