[GraphHopper] A method to handle barrier in junctions

[Peter]

Hi ZhiQiang,

thanks for this! You mean probably this issue:
https://github.com/graphhopper/graphhopper/issues/388

It is actually a bug in the tagging as the intended splitting was never
made for this as the OSM tagging for a barrier should happen on the way
not on the node. But see the full discussion there and maybe comment
your idea there.

Regards,
Peter
