nose_arg gives test finer granularity

nose_arg defaults to 'nitime', which will run all of the tests that can
be found for the package, but this argument allows you to test a subset
of the test suite, such as 'nitime.tests.test_timeseries' or even a
specific test using
'nitime.tests.test_timeseries:test_TimeArray_comparison'
Merge pull request #104 from ivanov/better-testing

nitime.test now allows for finer granularity

now `git shortlog -sn  rel/0.3...` does not cause Ariel to have split
personalities.
