Testing for base module and install profile

Simpletests are needed for all incubator functionality. Testing for submodules has been split out into a separate issue for each submodule; see http://drupal.org/project/issues/search/bahai_incubator?issue_tags=testing. Here are the issues for the incubator install profile and module itself:
