Cleanup - use and documentation of access/egress mode

[Andreas Tryti]

In the Transmodel API the documentation and how it actually works does not seem to correspond. This Issue sums up a few things to clarify and correct:

1. According to the documentation access and/or egressMode should default to foot if not set. However, if you set only accessMode you get no itineraries.
   ONLY accessMode does not work (if you set egressMode to foot explisitly it does work)

Example

2. If you search to a quay ID with only accessMode set it works. If you search with the position (lat/long) of the quay it does not work

Example

Testing the examples in dev I'm finding the correct result. It looks to me like this has been fixed and is rolling out.
