function names that include "test" at a word boundary

[pbstark]

There are still several function names that include "test," e.g., "greatest_name" and "test_count_on." Ideally, these should be re-named so that we can use nose for testing without any special configuration. Alternatively, we need a convention for where tests will live, and need to configure Travis CI to run only those tests.

[ron-rivest]

In the initial code development, these functions were included right with the
code that was being tested. Now they should be moved into separate module inside
the "tests" directory (where all the nosetests tests go). These include:
audit_orders: test_shuffle, test_audit_orders
election_spec: test_read_election_spec_general, test_read_election_spec_contests,
test_read_election_spec_contest_groups, test_read_election_spec_collections
groups: test_expand, test_expand_2
utils: test_count_on
("greatest_name" is not a test but is caught by the regex filter...)
