Implements parallel recursion for the partitioner Fixes osrm-extract's -dump-partition-graph: accept no further tokens References: - http://www.boost.org/doc/libs/1_55_0/doc/html/boost/program_options/bool_switch.html Pulls parameters through to make them configurable from the outside Defaults are equivalent to: ./osrm-partition \ berlin-latest.osrm \ --max-cell-size 4096 \ --balance 1.2 \ --boundary 0.25 \ --optimizing-cuts 10 Fixes parallel_do call for Intel TBB 4.2 (Trusty): no range-based overload
