[GraphHopper] How to find all the roads leading around a point

[dos65]

It possible, you should use low level api.
1) create graph
2) find closestNode by your lat, lon
3) create edgeExplorer from graph, edge iterator and iterating by them 
in your distance limit

Look to docs/core/low-level-api.md and any routing algorithm's sources.
