Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(name, *args, &block) ⇒ Object

  @configuration[name.to_sym] ||
      #fail(NoMethodError, "Unknown settings root \'#{name}\'", caller)
      nil
end

#load!(environment = nil, filename = resolve_path('config/eb.yml')) ⇒ Object

This is the main point of entry - we call Settings.load! and provide a name of the file to read as it’s argument. We can also pass in some options, but at the moment it’s being used to allow per-environment overrides in Rails
