Title: Enhance testing: run all executables

Speaking of style, this is an opinionated change; you may not like it.

Add a #! line at the beginning of each of the existing Python programs and change these files to be executable. This sets the stage for having the test script blindly run anything that is executable, adding support for testing many programming languages (including my little pipeline shell program).
