1) added 5 new tests for the group creation order
2) modified the h5dump test script to automatically generated non existing (new) output files
3) cleaning of unused DDL files
4) new modified DDL files include tcomp-3.ddl ( new form of named datatype) and the binary output files
tested : linux
macros in the dumper. this was basically adding a space after most of the '}'.
there are some places that don't have the space because those '}' were not printed
by the end_obj macro
