[Grace-core] 0..(size-1) or 1..size

[Andrew P. Black]

The answer (to me) is clearly 1 .. size.   That's how mathematicians index vectors and arrays, so it seems the natural default, and thus what one gets with a literal.

Naturally, the libraries will allow users to pick any specific lower and upper bounds that they want.

Please don't do that.  Instead, do

l.withIndexDo{ i, elem -> 
	print i
	print elem
}

The array knows what it's bounds are; the programmer doesn't have to.
