Excellent indeed!

And for gunner students of this game (wish I was one of those) the next
assignment is to extend this to work for ragged arrays...or maybe Steve the
gunner already did that?

I ask because a project I'm involved with could use the LUP facility right
away but would also need it for init_bounded_number_vectors etc...
