#5 updated the scripts for data import. createtags does now also have a version, to create a tag with description. And the data importscript does now set negative years to NULL, instead of skipping the datasets completely. Also included are the scripts to set the catalog statements and set up a cids system.
#5 Changed import for dataset with links to questions to import as 'order' function. Changed tablenames in create_importTable and importtable_to_cids, to match each other, for possible import without the need of changing anything.
#5 updated csw_create_view with the scope attribute displayed in csw and added a saperate file ('csw_create_array_accum') for the function, the view is using, to accumulate data into arrays.
