[studiawan]

I propose to add a plist parser for iOS CarPlayApp.plist. I will make a pull request for this parser.

@studiawan excellent, I've assigned the issue to you. Let us know if you're running into challenges writing the parser plugin

I'll let the tests run first and check with @Onager which one of us will do the review.
