Attn: Patch Re: iterating cell arrays

[David Bateman]

Trivial... Consider the patch at the end of this mail. This version
just iterates through all elements of an ND Cell array. It might be
better to also extract sub arrays of the ND Cell array, like what is
done for matrices in a for statement. The version of Matlab R12 I 
have access to does wierd things in this case, so unless someone
want to check the behaviour against a later version of matlab, I
think the version below is pretty much the best that can be done.
