ManyToMany with Turn Penalty

[YangYang1208]

Is there a way to do ManyToMany routing that includes turn penalties? I've explored all matrix algorithms, yet not a single one seems to accept turn penalties as an input.

I've also looked into the sample code and issues #307 and #313. However, when I try to run the following sample code on my own routerDb (which is contracted), I get the "Value cannot be null. Parameter name: nodeBasedGraph" error.

route = router.Calculate(car, locations, turnPenalty: 120, preferredDirections: null);

Any pointers would be very appreciated.
