ValueIterator
ValueIterator is used to iterate over an array type DocView
next
`void spino_value_iterator_next(SpinoValueIterator* iter)`
Moves the iterator along to the next element of the array.
get_view
`SpinoDocView* spino_value_iterator_get_view(SpinoValueIterator* iter)`
Returns a DocView of the array element that the iterator points to.
compare
`gboolean spino_value_iterator_compare(SpinoValueIterator* iter, SpinoValueIterator* other)`
Returns True if iter and other point to the same node, otherwise false
is_not
`gboolean spino_value_iterator_is_not(SpinoValueIterator* iter, SpinoValueIterator* other)`
Return True if iter and other do not point to the same not. The opposite of compare()
