 Notes:
 - Recommend that you run 'RemoveDoubles' on each imported mesh after using this script
 - Blocks are created on layer 19 then referenced at each insert point.
-- Big DXF-files (over 1500 objects) decrease import performance. The problem is not the inefficiency of python-scripting but Blenders performance in creating new objects in his database - probably a database management problem.
