This structure contains optional controls for PK_BODY_ask_topology

Used in:

PK_BODY_ask_topology

The fields are as follow:

'want_fins'         This controls whether fins are to be included in the
                    output.
                    When it is set to PK_LOGICAL_false (the default):
                    - the children of a loop are edges with a sense indicating
                      whether the edge is in the same or opposite direction
                      to the loop,
                    - non-manifold edges have loop children with a sense
                      indicating whether the loop is in the same or opposite
                      direction to the edge.
                    When it is set to PK_LOGICAL_true:
                    - the children of a loop are fins each with the sense
                      PK_TOPOL_sense_none_c
                    - each fin has exactly one edge child with a sense
                      indicating whether the edge is in the same or opposite
                      direction to the fin.
                    - non-manifold edges have fin children with a sense
                      indicating whether the fin is in the same or opposite
                      direction to the edge
