17 * All structures are reference counted to allow reuse without duplication.
18 * A *_copy operation will increase the reference count, while a *_free
19 * operation will decrease the reference count and only actually release
20 * the structures when the reference count drops to zero.
22 * Functions that return an isa structure will in general _destroy_
23 * all argument isa structures (the obvious execption begin the _copy
24 * functions). A pointer passed to such a function may therefore
25 * never be used after the function call. If you want to keep a
26 * reference to the old structure(s), use the appropriate _copy function.

33 * n_in is the number of in variables
34 * n_out is the number of out variables
35 * n_in + n_out should be equal to set.dim
