Prior to this commit, the handlers and code objects which dealt with puppet functions were referred to as `FutureParserFunctions` and `ParseFunctions`. This naming convention will not make very much sense going forward when the future parser becomes the primary parser. Therefor, rename `FutureParserFunctions` to `Puppet4xFunctions` and `ParserFunctions` to `Puppet3xFunctions`.  |
