int FindLeftTurnEdge

int bowtie_v,
TArray< int > & bdry_edges,
int bdry_edges_count,
const FIndexFlagSet & used_edges

Remarks
Ok, bdry_edges[0...bdry_edges_count] contains the boundary edges coming out of bowtie_v. We want to pick the best one to continue the loop that came : to bowtie_v on incoming_e. If the loops are all sane, then we will get the smallest loops by "turning left" at bowtie_v.
