packarray - version 0.2

[Chris Frey]

Hello fellow coders,

Version 0.2 of the packarray class is available at the same spot:

	http://www.netdirect.ca/~cdfrey/software/packarray.cc

This version handles endian issues all at once, and converts double
values to network byte order as well.  The basic_field<> class is gone,
as it's not needed any longer.

I ran into an interesting issue with regards to C++ aliasing rules, which
you can read about here:

And here:

	http://mail-index.netbsd.org/tech-kern/2003/08/11/0001.html

This makes me rather concerned about the reinterpret_cast<> I have to do
in 4 places in packarray.  Any tips on how to clean that up would be very
much appreciated.

Anyway, it works great for me, even with g++ 4.0.2.  Testing on non-intel
machines would be great.

Enjoy,
- Chris
