remove empty unit test remove compiler directives move trip related files from routing_algorithms to algorithms run clang-format on files fix all std::size_t related issues improve code by adding std::move()s clean up includes fixing several code stye and improvement issues add several small code improvements return single scc in SplitUnaccessibleLocations() when theres only one change ComputeRoute() to return an InternalRouteResult by value improve some code style issues
