Evaluates Ruby examples in MD files.

It looks for code blocks starting with '“`ruby'. The blocks are evaluated in same order as they appear in the markdown file. Each top_level parseable piece of code is evaluated and the value is added as a comment, e.g.:

# Title

First evaluated block:

```ruby
a = 1 + 2
def a; :a; end #
[a,
 :b]
```

Continuing in next block

```ruby
a
```

becomes

# Title

First evaluated block:

```ruby
a = 1 + 2         # => 3
def a; :a; end
[a,
 :b]              # => [:a,:b]
```

Continuing in next block

```ruby
a                 # => 3
```

A parseable piece of code ended with '#' will be evaluated but its result is not added to the output as a comment, which is useful for method and class definitions.
