be_a_new matcher

The be_a_new matcher accepts a class and passes if the subject is an
instance of that class that returns false to persisted?

You can also chain with on be_a_new with a hash of attributes to specify
the subject has equal attributes.

Scenarios
example spec with four be_a_new possibilities
Given
a file named "spec/models/widget_spec.rb" with:
require "spec_helper"

describe Widget do
  context "when initialized" do
    subject { Widget.new }
    it { should be_a_new(Widget) }
    it { should_not be_a_new(String) }
  end
  context "when saved" do
    subject { Widget.create }
    it { should_not be_a_new(Widget) }
    it { should_not be_a_new(String) }
  end
end
When
I run rspec spec/models/widget_spec.rb
Then
the examples should all pass
