Simple Memoization for Ruby 2.0+.

### Differences between Memoist & Memoist2

Unlike [Memoist], this is **not** a drop-in replacement for old ActiveSupport::Memoizable. Memoist will still work just fine for that if you're using Ruby 2.0+. This project, on the other hand, is just me playing using Module#prepend which makes this stuff very simple.

**[Memoist]**

  * Works on all Rubies.

  * Is quite complicated.

  * Has the exact same api as `ActiveSupport::Memoizable`.

**Memoist2**

  * Only works on `Ruby >= 2.0.0`.

  * Is deliberately much simpler.

  * Has a slightly different API that could totally change.

Example

-------

Memoize an instance method

    class Foo

      include Memoist2

  

      def bar

        sleep 1 && 2**10

      end

      memoize :bar

    end

Memoize a class method

    class Foo

      include Memoist2

  

      def self.bar

        # something expensive

      end

      memoize_class_method :bar

    end
