Testimony

- Support added to accept test modules as input (Only directory was supported
earlier)

- Code refresh

- Major code refactor for modularizing the code
- Added Tags support
- If `Test` is not present, the first line of docstring will be used instead

- json support now incorporated

- Bug fix: manual vs automated test count is wrong when the test cases are
written with "status" tag vs. "Status"

- fix to check the tests starting with `test_` rather than just `test`
- Testimony will return error code when docstrings are missing, incorrect
docstrings found, minimal docstrings not present
- Make validate_docstring return a 0 success return code if no errors are
found
- Organized Constants
- Now Testimony accepts --nocolor or --n argument to avoid color output
- Testimony will now not error out if termcolor is not installed.
- Make termcolor an optional dependency
- Add Travis configuration to automatically run pep8 when Testimony is
updated
- Get tests from subfolders of the given path
