> Related to fixing PDFBOX-4003 - a number tree can hae several levels. Currently the merge
code expects a NUMS array, but it can also have KIDS. So the code must be changed so that
it uses the new convenience class to handle a number tree in full. See also code comment
> {code}
> //TODO this code only works with flat number trees.
> // It should be a PDNumberTreeNode, but that class is broken because
> // COSBase can't be instanciated and because the tree elements can
> // be an array or a dictionary
> // example of file with /Kids: 000153.pdf 000208.pdf 000314.pdf 000359.pdf 000671.pdf
> // from digitalcorpora site
> {code}
