a crappy form of post-order traversal which really does not belong here.  While
we are at it, improve documentation and use a vector instead of a stack.

run down the curtain, and joined the bleeding choir invisibile!! THIS IS

Eliminate the old LateResolveValues data structure, replacing it with a
new, simpler, ForwardReferences data structure.  This is just the first
simple replacement, subsequent changes will improve the code more.

This simple change improves the performance of loading a file from HDF5
(contributed by Bill) from 2.36s to 1.93s, a 22% improvement.  This
presumably has to do with the fact that we only create ONE placeholder for
a particular forward referenced values, and also may be because the data
structure is much simpler.
