* Finds all the objects that appear at least in some of the catalogues

* All the catalogues
* @param ncats
* Number of catalogues
* @return
* The matching table if sucess, NULL otherwise.

*
* Implementation notes:
*
* cat_indexing_order tells you in which order the catalogues are being
* iterated. For example cat_indexing_order[2] gives the index of the
* catalogue that is being iterated in the 3rd postion.
