Previously the usage of the yaml_dumps module was causing any python unicode key and value to show up as: 'item': !!python/unicode "some string" This was not very pretty... Fix this by using safe_dumps (which is also a good thing to use and allow_unicode=True). Also create a tiny helper function in the cc_debug module that does not include the yaml start and end footers (since this module has its own footers and headers). Also includes a basic sanity test for this module.
