Added "Hellope, Lua!" example

[RobinsAviary]

Here's that simpler "Hello World" example I was talking about, though I made it "Hellope, Lua!" because of Odin. It compiles no problem as well :) If you think this is too simple for an example/the other example is good enough though, I totally understand. Let me know what you think! Thanks!
