Samples? #233

Can there be a samples directory with an .md file on how to run them? ("run npm install, run npm run build")?

I think, the following samples could be beneficial:

1. "99 bottles of beer". Calls itself recursively starting from 99, special casing 1.
2. "sort numbers" - an equivalent of the following Haskell code:

quickSort []     = []
quickSort (x:xs) = quickSort (filter (<x) xs)
                   ++ [x] ++
                   quickSort (filter (>=x) xs)

3. Consume a FunctionalScript function from "existing" TypeScript project
4. Consume a FunctionalScript function from "existing" JavaScript project
5. Probably, "Hello World" (just to cover another classic example)
6. A parser? (where functional languages are strong). Could be a URL or DateTime parser.
7. Expression calculator (+, -, /, %, (), maybe pi constant, log2(), sin(), cos() etc) - the stuff similar to what a typical hardware calculator has.
