How is that different from:
Allocating all the arrays as one n+1 dim and grabbing rows from it
is faster than allocating the small arrays individually.
I am iterating too many times to allocate everything at once though.
I can just do a nested loop
where create manageably large arrays in the outer
and grab the rows in the inner,
but I wanted something cleaner.
