This function returns the set of fins in the given body.


Depending upon the configuration of the 'body' ( see PK_BODY_ask_config ) this
function returns:
    PK_BODY_config_standard_c      all fins of the standard 'body'

    PK_BODY_config_compound_c      all fins of all children of the
                                   compound 'body'

    PK_BODY_config_child_c         all fins of the child 'body'

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