First, install it:

```bash
$ gem install tacky
```

Then, use it like this:

```ruby
require 'tacky'
obj = Tacky.new(obj)
```

That's it, all method calls will be cached. This means that only the first
call of any method will actually reach your object. All consecutive calls
will be intercepted by the `Tacky` decorator, which will return
previously calculated values. The decorator keeps all values in its internal
`Hash`.

If you want all methods of everything your methods return be cached too, you
need to use "deep" caching (it's `true` by default):

```ruby
obj = Tacky.new(obj, deep: true)
```

Keep in mind that `Tacky` is thread-safe.
