* random value generator.
* cut_generate_uuid.
* rename cut_process_* to cut_child_cutter_*.

  e.g. cutter --filter-by-attribute 'target_version <= 1.0.0'.
* report errors in data setup function.
* add CUTTER_DEBUG technique in test/run-test.sh to tutorial
  as a debugging technique.
* use real data instead of dummy data (e.g. a, b, c, ...)

* auto-cutter.
* gompertz curve.
* elapsed time assert. (compare with past elapsed time?)
* test history chart.
  * N tests
  * N failures
  * elapsed time
* coordinattion with TestLink.
* failmalloc like memory test.
* update option descriptions in README.
* introduce easy sub process debugging mechanism.
* GTK+ UI supports test iterator.
* cut_get_test_name().
* cut_{get,set}_current_test_context() ->
  cut_{get,set}_test_context()
