vectors, arrays, etc

[Kim.fateman@Berkeley]

I believe that for many future applications, the most important type of vector
or array is one that corresponds to the data format of the Fortran or
other numerical compiler system on the same computer.  If, for example,
VAX common lisp does not have this, I believe some potential
users will be unhappy.
Whether this should be done as a primary data type or as
an optimization, is probably irrelevant if it works.
