(
--- received arguments ---
PK_FIN_t        fin,               --- a fin

--- returned arguments ---
PK_FIN_t *const next               --- the next fin around the edge
)


This function returns the next fin in order around the given fin's edge.


This function could be used in conjunction with PK_EDGE_ask_first_fin to
scan the fins in an edge, one at a time, in the same order as returned
by PK_EDGE_ask_fins. The ordering is cyclic, with the first fin being
returned again after the last.
