Routers suggestion - accept functions for options

[frnora]

Hi,

I am trying to figure out the best way to have the manhattan router always come and go to the preferred side.

As title suggests, I think it would be nice to be able to provide functions for some of the router options. Namely:

1. manhattan: endDirections and startDirections
2. metro: endDirections and startDirections
3. rightAngle: sourceDirection and targetDirection

Currently the default router needs to be replaced or its args updated which (most likely) means it needs to be then restored to the default value later on.

Thanks for reading.

You can wrap the manhattan router in a function and determine the arguments e.g. startDirections inside this function.
