Comments & README

- refactored WorkflowValidator.validationErrors as errors to keep
  consistancy with the underlying validator and other validators
- added missing comments
- fixed README `Add as dependency to your project`, used the scoped name
- added imports in README examples
- added 'validate parts of a workflow' example in README
