Fixing D204, D205, and D207 PEP257 violation.

Currently tox ignores D204, D205, and D207.
D204: 1 blank required after class docstring.
D205: Blank line required between one-line summary and description.
D207: Docstring is under-indented.
This change removes  D204, D205, and D207 ignores in tox and fix violations.
