Hi all,

- removed "make examples" functionality from Makefiles.
    On Joe's advice I removed the ability to make all of the examples in the
    xmds/examples directory.  This actually made my life easier, so that was 
    all good :-)
- improved binary output functionality
    Binary output no longer has the redundancy inherent in the ascii output 
    format.  The arrays are written to file, first with an unsigned long
    integer giving the number of points to come, and then the vector of
    points, repeating to the end of file.  loadxsil.m has been changed to
    reflect these changes.  The advantage of the change is that the output
    data files can now be quite a bit smaller than the corresponding ascii 
    output.  The simulation also now checks for littleendian or bigendian 
    binary behaviour, and writes which to the .xsil file.  This means that
    loadxsil.m can now read files from any platform, since it now checks
    for the "endian-ness" of the data files from a flag in the .xsil file.
    I've tested this on LinuxPPC and LinuxX86.  This change also requires
    endian.h to be on the system, and I've changed the configure script to
    check for this also.
- command line arguments to simulation binaries
    The output binary file can now take arguments on the command line.  This
    allows people to change global variables of the simulation at execution
    time of the binary instead of having to rerun xmds and compile a new
    binary for a minor change of parameters.  To use this feature, put the 
    variables that you want to use inside   tags in the 
    section.  For instance moo baa defines two new variables to
    accept at the command line of moo and baa.  There are some limitations to
    the current implementation though (I'm working on a better system now,
    but I thought the current implementation might be handy for a while).
    The limitations are that the variables listed have to be double's, and
    they have to be entered at the command line in the order listed in the
     tags.  The program does, however, check that you've entered the
    right number of arguments at the command line, and prints the usage if
    you get that wrong.  However, if you want to put in an int, or a char *
    you might have problems atm.  Like I said above, I'm working on using
    Gnu getopt going, and have been making some progress with that.
- housekeeping stuff
    I've removed the Configure script from the repository.  This was the 
    original way of "configuring" xmds.  I've also removed the Makefile in 
    the xmds/source directory from the repository.  The Configure script
    and the Makefile are now made obsolete by the use of Gnu autoconf.

I think that's it at the moment.  Hope everyone is well, and that you're
finding the changes useful.

Later
