Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method_name, *args, &block) ⇒ void

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

For each method called we verify if it's an defined attribute for the builder. If it is then we store the argument as value of the attribute
