v0.2.0

This release is cleaning up the mocks.Diff/mocks.Equal setup concept removing the before to complex config approach. The default DiffConfig is now updated using SetArg(mock.DefaultDiffConfigName, config) replacing the previous mocks.Config(ConfigFunc...) pattern. To simplify configuration, DiffConfig now supports a fluent update interface.

Besides, the pull request is improving code quality and the documentation.
