--- returned arguments ---
int       *const n_fins,            --- number of fins (>= 0)

This function returns an ordered list of fins connected to the given edge.


The fins are ordered according to their spatial orientation around the edge.
Looking in the direction of the edge, successive fins in the array are
listed in clockwise order.

The output array 'fins' is optional. If it is set to NULL, the function
will only compute the number of fins around the edge.
