testing -- test frame mode

[Fred T. Hamster]

the test framework used by all the unit/acceptance tests
is needed, but it's already there...
mostly.

take a flag for --unit
or for --acceptance
to decide how to run test.

--unit means just run through once to verify basic func,
even though with some random values.

basis array test is the archetype;
make it able to do one run through,
keep random data idea,

need a flag for --runs to set the max runs through the main loop.

also a flag --time for how long to allow it to run;
just loops until hits the timeout.
