fast regret does not work with initial routes

> I am trying to use it with initial routes, but no solution is generated. If I remove "Jsprit.Parameter.FAST_REGRET", the solution is generated. I don't know why is that.

allow multiple depot-bounded round tours with one vehicle

If the vehicle routing problem is modeled with services, vehicles can only conduct a single round tour. If one requires multipe round tours, one needs to model it with shipments....

Will be availabe with #481 soon.

also if they are empty. This does not only mean that they need to appear as "empty" vehicle route in the solution, but also that the algorithm knows that they...

Currently, it is easily possible to account for multiple capacity dimensions, i.e. one can specify static limits. For example, a vehicle can load 10 items of type A, 15 of...

Assume there is a motorbike that can load 10 items of A in bags of both sides of the motorbike. The only way to model this is capacity -> [20]...

making vehicles and jobs immutable again

@michalmac suggests "to create copies for internal use just before optimisation starts (it is not much of an overhead), while at the end, the original objects will be referred to...

make constraints as atomic as possible

to let the user decide which constraints are really needed. by default, jsprit is configured such that it can solve many problems. This, however, comes with significant costs ...

since it is actually GreedyAcceptance. For example in the xsd-file [here](https://github.com/jsprit/jsprit/blob/master/jsprit-core/src/main/resources/algorithm_schema.xsd#L118) and in many examples
