GitHub Action for running cpplint commands

Each time that new code is pushed into your repo, you can have a cpplint command automatically run.

Example workflow:

• Put the following text into a file named .github/main.workflow in your repo):

workflow "on push" {
  on = "push"
  resolves = ["GitHub Action for cpplint"]
}

action "GitHub Action for cpplint" {
  uses = "cclauss/GitHub-Action-for-cpplint@master"
  args = "cpplint --recursive ."
}

Or to add other cpplint options to args = above.

Syntax: cpplint.py [--verbose=#] [--output=emacs|eclipse|vs7|junit]
                   [--filter=-x,+y,...]
                   [--counting=total|toplevel|detailed] [--repository=path]
                   [--root=subdir] [--linelength=digits] [--recursive]
                   [--exclude=path]
                   [--headers=ext1,ext2]
                   [--extensions=hpp,cpp,...]
