Literate CoffeeScript

Literate Coffeescript allows you to write code as Markdown documents and when compiled, the indented blocks are treated as code and the rest is ignored as comments.

Literate programming is a methodology that combines a programming language with a documentation language, thereby making programs more robust, more portable, more easily maintained, and arguably more fun to write than programs that are written only in a high-level language.

We have a lot of crazy logic because of always-flexible business rules. Writing in a more verbose, natural way to describe why we have an odd snippet of code would make it easier for someone else to come back to later.

Here's a quick example of how we could rewrite for loops that populate an array in a more coffee-like manner
