Thanks for the comments @cliffclick . I'll work on ArrayUtils and
Vec.makeZero() usage.
Regarding row labeling, I wanted to keep the operator inner-loop free of
if() and else to skip first row optionally (i.e keep the inner loop focussed on
just the math.) However, now that I think, it should be possible to filter out
the label vec optionally even before entering MRTask, and have both the matrix
and row labels within the same Frame.
I'll work on these comments and re-post. Thanks!
