[osis-core] Is this ready for OSIS 1.1? Overlapping heirarchies

[Todd Tillinghast]

There seems to be little help for multiple overlapping heirarchies.

There was Troy's points about what would seem reasonable as move complex
releases come about.

Did we say that a <verse> element can never be split and that a verse must
always be represented by multiple <seg> elements?  If not why do we have
<seg>?

How do we handle the cases previously brought up regarding Matt 13?  These
are not hypothetical cases but real cases.
