Add TEST_RANGE to specify arg ranges in parameterized tests

Browse Source 
TEST_RANGE([start, stop, step]) generates following runs of the test
function: test(start), test(start + step), ..., test(start + n * step),
where start + n * step <= stop. The step must be positive.

If the test function takes several arguments, the following syntax must be used:
TEST_RANGE([arg1_start, arg1_stop, arg1_step], ..., [argN_start, argN_stop, argN_step])

This addresses issues #53 and #144.
