including the initialization statements.

5aa7dc5daf adopt suggestions from Bentley and McIlroy (SP&E Nov 1993)
to make qsort more robust:

	* use "ninther" to choose pivot.
	* use three-way partition to avoid quadratic
 	  behavior on all-one-value arrays.

also add tests suggested in that paper.

the immediate cause of the slowness we observed was
in fact none of these: the recursive call was sorting
data[0:m] instead of data[a:m].

also rename package to "sort" to match convention.

3c2f0ae132 * pretty printing snapshot: towards printing comments nicely
- implemented elastic tabstops algorithm, now correct and documented
- first cut at printing comments (use -comments flag, disabled for now)
- struct field types are now aligned (using elastic tab stops)
- needs more fine-tuning

* fixed a bug in test script
* added quick smoke test to makefile and invoke it in run.bash
  instead of the full test
