Transpile Ruby code to JavaScript in JavaScript!

## Usage

Given a Ruby file named `hello.rb`:

```ruby

puts "Hello world"

```

The following code will transpile `hello.rb` to JavaScript:

```javascript

const Builder = require('opal-compiler').Builder

// Opal object will be available on the global scope

const builder = Builder.create()

const result = builder.build('hello.rb').toString()

console.log(result)

//(function(Opal) {

//  var self = Opal.top, $scope = Opal, nil = Opal.nil, $breaker = Opal.breaker, $slice = Opal.slice;

//  Opal.add_stubs(['$puts']);

//  return self.$puts("Hello world")

//})(Opal);

```
