Comment(by strk):

 Example outputs:
 {{{
 {"type": "LineString", "arcs": [42, 43]}
 {"type": "Polygon", "arcs": [[42, 43], [44]]}
 }}}

 The numbers in square brackets (array elements) are "arc identifiers",
 pretty much like our edge identifiers except they are (0-based) indices
 into an array, which we'll need to build somehow.

 Also, backward arcs/edges are expressed with -(INDEX+1)
