I'm taking advantage of the instance's eigenclass, or metaclass. All ruby object have an eigenclass. The eigenclass is sort of like a ruby object's own copy of the class definition. It enables adding singleton methods to a particular instance of a class.

The different between calling `def_delegators` on the instance's eigenclass vs calling it directly on object's class, is that I only want to do delegate the helper methods for one instance of `Bldr::Node`, rather than every subsequent instance of the `Bldr::Node` in the runtime. The reason for this is that different rails controllers (and their `ActionView::Base` instance counterparts) will have unique modules of helper methods.

```ruby
class Bldr::Node
  def initialize(*args)
    (class << self; self; end).attr_accessor 
  end
end
```

Here's a working example of eigenclasses in action: https://gist.github.com/ajsharp/5360447.
