Claude Warren commented on LANG-1387:
-------------------------------------
It is not a collection in an of itself. a Span has not contents. It might be
useful with a collection or on top of an array but it does not have the
contents.
Is there a reason not to put it in lang?

> # determine if one span contains another span
> # determine if two spans overlap
> # do not have to have 0 (zero) as the index origin.
> # determine the length of the span
> # determine the last position in the span.
> # determine the first position in the span.
> Changes to Number Utils required to detect underflow and overflow
> calculations.
