At last! I have finished the Quesa changes.

[Roger H. <rog...@mi...>]

I have now finished all the changes I set out to make to Quesa, and a 
few more.

I hope you all like what I've done but as they say, your can't please 
all the people
all the time.

Though I have worked in a way to minimize any possibility of 
introducing bugs there
is always a risk, so please let me know if you think there is a fault 
in my code which
was not in the original.

There might be the odd file I decide to tidy up a bit but this will be 
one or two files at
a time, I will not be committing 25 files at a time again without 
discussion with the group.

Due to the non standard way E3Renderer and the Input / Output classes 
add their
methods (directly not through via their Meta Handler) I have been 
unable to convert
these to have their addresses in their class info, so they continue to 
work via the
hash table. For I/O this is not too much of a problem as it is slow 
anyway as it takes
time to transfer the data to/from disk. E3Renderer is more of a 
problem, and if
someone who understands it can either convert it to Meta Handler 
working (so I can
convert it) or convert it themselves (allowing for plug in renderers of 
course, which
do use Meta Handler working) then that would be great.

I am going to be working on other projects from Monday.

Roger.
