RSpec matchers

[aried3r]

Would you be interested in shipping RSpec matchers with this gem?

I only have two in mind actually for now:

# unread_matchers.rb
RSpec::Matchers.define :be_readable do
  # check to see if the model has `acts_as_readable` declared on it
  match { |actual| actual.is_a?(::Unread::Readable::InstanceMethods) }
end

RSpec::Matchers.define :be_a_reader do
  # check to see if the model has `acts_as_reader` declared on it
  match { |actual| actual.is_a?(::Unread::Reader::InstanceMethods) }
end

# message_spec.rb
it { is_expected.to be_readable }

# user_spec.rb
it { is_expected.to be_a_reader }
