Fixed maxSpeed bug for bike and route=road will be avoided. Not all tests pass but it looks like routing prefers off road which is a good sign
towards #190, todo: use prefer weighting
bike encoder: introduce collect to make an easy to overwrite mechanism for priority
bike: less influence from priority
moving prio calc into priorityWeighting to make sure getPriority always returns [0, 1]
priorityWeighting: fixed wrong order; other integration tests fixed, still some obstacles to do
handlePriority now always called
