-/* This structure encapsulates huffman and VQ style encoding books; it
- doesn't do anything specific to either.
-
- valuelist/quantlist are nonNULL (and q_* significant) only if
- there's entry->value mapping to be done.
-
- If encode-side mapping must be done (and thus the entry needs to be
- hunted), the auxiliary encode pointer will point to a decision
- tree. This is true of both VQ and huffman, but is mostly useful
- with VQ.
