Summary: SVD gives an error: The function (COMMON-LISP:SETF MATLISP:D

Initial Comment:
It looks like setf (diag ...) is not defined properly or is not in the correct package.  When I run svd with job :a I get:

The function (COMMON-LISP:SETF MATLISP:DIAG) is undefined.

Message:
You should be doing:
 (copy! s (diag~ s1 0))

I'll add a setf-able method to the branch. 

We decided to use "~" (like the "!")  to refer to functions 
which give out matrix-slices.

Message:
I found the definition in tensor.lisp, but am not sure why it can't be used
in svd.lisp.  So, I substituted the expansion in place in the svd method
definition and now I get a new error when running svd with job :a

Arguments X,Y to COPY! are of different dimensions.

Where I substutite I found the definition in tensor.lisp, but am not sure
why it can't be used in svd.lisp.  So, I substituted the expansion in place
in the svd method definition and now I get a new error when running svd
with job :a

Arguments X,Y to COPY! are of different dimensions.

Where I substutite (copy! s (diag s1 0)) for (setf (diag s1) s).
