Assumptions

• Taps are in order of id/date so no sorting is required.
• The reviewers of this code understand my experience is mainly .Net which made things more difficult. For example, knowing which file reading/writer to use.
• If there is no known cost for the trip eg stop doesnt exist, use 0. Log this information to monitoring with alerts.
