#*
#* Unit test for the COD::CIF::Tags::Manage::set_loop_tag() subroutine.
#* Tests the way data item insertion into the loop affects the overall
#* order of loops in the data block.
#*
#* Where possible the loops should not change their order of appearance:
#* 1) insertion of new data items should not affect the loop order;
#* 2) newly formed loops should appear at the end of the data block
#*    regardless if they are formed from new data items or the already
#*    existing ones.
