v0.0.3

Changed

• Filtering out yaml files from the dockerfile sources since all three dockerfile linters
  use yaml files as their configuration files. (#12)

Fixed

• Changing dockerfilelint rc file to an empty file since dockerfilelint doesn't handle an empty rules list. (#11)
• Adding issues to the statick output if one of the dockerfile linter plugins throws an error while parsing
  the output from its tool. (#11)
• Adding dockerfile_lint to npm dependency file. (@gregtkogut, #10)
