2.2.0 (2016-06-21)

Extracts command behaviour to Skywalker::Callable and Skywalker::Transactional.

This simplifies the Command object, making it basically a combination of Callable and Transactional mixins. It also allows for the reuse of the constituent parts on a larger scale.
Remove dependency on ActiveRecord.

We now do a check to see if ActiveRecord is defined. If not, we simply default to calling the passed block. This allows us to avoid having to require ActiveRecord, which lightens our dependencies and also makes us feel just a tiny bit less dirty.

2.1.0 (2015-05-14)

Yields self to any block given to any object implementing Skywalker::Acceptable.

This has a few ramifications; first, it allows some easy extension simply by passing a block to the constructor, as such:

a = MyObject.new(an_argument: :foo) { |instance| instance.an_argument = :bar }
a.an_argument # => :bar

More importantly, it allows for simpler subclassing:

class MyCommand < Skywalker::Command
  def initialize(*args)
    super do
      a_symbol = :new_symbol
    end
  end
end

Refactors guts of commands to extract kwarg instantiation pattern into Acceptable module.
Improves inline documentation.

Add required_args, which allows marking certain attributes as required at initialization. Defaults to an empty list.
Add testing section of README.
Add example files.
