@tags[ :@docstringIC:YARD::Docstring"‡Usage:
MailEngine::ZipProcessor.extract_all_files(path, ["css", "jpg", "gif"]) do |file_path|
  Image.create :file => File.open(file_path)
end

Params:
zip_file_path => /path/to/your/zip_file
needed_exts => ['jpg', 'jpeg', 'css']

Result:
the first item of array is file paths you needed and extracted from zip file.
the second item is the unzip path.
