Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method, *args, &block) ⇒ Object (protected)

Magic predicates. For instance:

capability.force?                   # => !!options['force']
capability.shebang                  # => "/usr/lib/local/ruby"
capability.test_framework?(:rspec)  # => options[:test_framework] == :rspec

need to rewrite this for deep hash entries use capability to group mapping
