    Description

      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:

      let(a=memset(random(collection1, q="*:*", fl="field1, field2", rows=10000),
             cols="field1, field2",
             vars="c, d",
             size=10000),
    e=corr(c, d))
