Closes #71.

Hello,

thanks for your idea and first version of PR. 👍

Nice - this works, but...:

• File parallel-lint.php is base file for tool. It is not good place for show versions.
• Source of code has class Settings [1]. I mean it is better place for check input parameters.
• Maybe is in source better place where is possible define and run function showVersion.

Sorry for my critics comment. I mean that my reaction helps you with better code. I can help you - ask me, when you can :-)
