Right I've been playing with this today.

I have got it looping by doing this:

foreach($odoc->termlist_begin() as $key=>$term){
	echo "{$key}: {$term} <br/>";

Key is just integer starting at 0. I am just returning the term for now
as debug. I am planning return the TermIterator, however I have hit
against an issue.

The issue is that foreach needs to know when it hits the end of the
loop. Is there anyway of a TermIterator knowing its the end? I've had a
look at the api and I can't figure it out. I can get the end
TermIterator from the Document but I can't use that if I want to do a
true foreach. I suppose I could pass the end iterator when I call
termlist_begin() but I'd rather use in-build xapian calls.
