Updating feature file for deliver to include new multiple output and fileset filter classes
initial commit of multi output design
Sample of new YAML format, contains targets per the design meeting.
Changed so that init has target_name as an additional arg. This was necessary, since job_stream.rb iterates over each target, and the sub-hash passed to instantiate output.rb does not contain the target name.
Removed Sam's address, added Josh, Julie, and Scott's email address -- this is convenient for testing, and will change once we create a unique addresses.yaml for each env.
Changed to create one Output object per 'target' found in an email YAML config.
Modified to reflect new 1 arg Output class constructor. Replaced identity comparison with equality, i.e, s/==/.eql?/ .
Removed 'name' member variable and its attr_reader generator, as this field/method are not used anywhere.
