Title: Support for instance variables

Support for instance variables. Following is sample. Let me know if you have any questions.

The sample class
```ruby
class Person
def initialize
@retired = false
end
end
```

Without the support:
```ruby
describe '.initialize' do
subject { Person.new }
it('will not be retired') { expect(subject.__send__('retired')).to eq false }
end
```

With the support
```ruby
describe '.initialize' do
subject { Person.new }
its('@retired') { is_expected.to eq false }
end
```
