 The flagging of both _odd vs. even remaining partial path length_ and _leaf vs. extension node_ as described above reside in the first nibble of the partial path of any 2-item node. They result in the following:
 
-    hex char    bits    |    node type partial     path length
-    ----------------------------------------------------------
-       0        0000    |       extension              even
-       1        0001    |       extension              odd
-       2        0010    |   terminating (leaf)         even

 For even remaining path length (`0` or `2`), another `0` "padding" nibble will always follow.
