# Dicer

useful DCI for Rails.

for example:

```ruby
class User < ActiveRecord::Base
  has_many :purchases
end

module Customer
  include Dicer::Behavior

def purchase(book)
    self.purchases.create(book: book)
  end
end

class PurchaseContext < Dicer::Context
  describe User do
    it_behaves_like Customer
  end
end

context(PurchaseContext.new)
user = User.where(id: session[:user_id]).first
book = Book.where(id: params[:id]).first

user.purchase(book)
```

Dicer is faster than `#extend` and `SimpleDelegator`
