-/*A node in the Huffman tree.
-  Instead of storing every branching in the tree, subtrees can be collapsed
-   into one node, with a table of size 1<<nbits pointing directly to its
-   descedents nbits levels down.
-  This allows more than one bit to be read at a time, and avoids following all
-   the intermediate branches with next to no increased code complexity once
-   the collapsed tree has been built.
-  We do _not_ require that a subtree be complete to be collapsed, but instead
-   store duplicate pointers in the table, and record the actual depth of the
-   node below its parent.
-  This tells us the number of bits to advance the stream after reaching it.
-
-  This turns out to be equivalent to the method described in \cite{Hash95},
-   without the requirement that codewords be sorted by length.
-  If the codewords were sorted by length (so-called ``canonical-codes''), they
-   could be decoded much faster via either Lindell and Moffat's approach or
-   Hashemian's Condensed Huffman Code approach, the latter of which has an
-   extremely small memory footprint.
-  We can't use Choueka et al.'s finite state machine approach, which is
-   extremely fast, because we can't allow multiple symbols to be output at a
-   time; the codebook can and does change between symbols.
-  It also has very large memory requirements, which impairs cache coherency.
