EmbedSimplePath

(
    bool bUpdatePath,
    TArray< int >& PathVertices,
    bool bDoNotDuplicateFirstVertexID,
    double SnapElementThresholdSq
)

Embed a surface path in mesh provided that the path only crosses vertices and edges except at the start and end, so we can add the path easily with local edge splits and possibly two triangle pokes (rather than needing general remeshing machinery)
