> The *memset* function copies multiple numeric arrays into memory from fields
> in an underlying TupleStream. This will be much more memory efficient then
> calling the *col* function multiple times on an in-memory list of Tuples.
> Sample syntax:
> {code:java}
> let(a=memset(random(collection1, q="*:*", fl="field1, field2", rows=10000),
> cols="field1, field2",
> vars="c, d",
> size=10000),
> e=corr(c, d))
> {code}
