Improved struct module

[Mike Fletcher]

I too have many cases where I would like to use C-structure-like data
packing functions.  1/2 of the cases are related to the reading of binary
3-D file formats, where the definition of the file is a structure of
structures linearised to disk using count,data formats.

File := header, pointset, connectionset, normalset, skinset
pointset := count,point*count
point := float x, floaty, floatz

The other 1/2 of the cases is in the creation of multi-user virtual reality
wire protocols, where you want to be able to create similar highly
structured data types (i.e. you might have 20 different structures in
various relationships) and dump/load them across the wire.  Of course, here
you would also like various data-reduction features (e.g. unicode style
"continuation" encodings of integers and strings, bitfields etc.), but
that's just me being greedy :) .

Cheers,
Mike
