Make Activerecord Observers not load observed models -> faster/safer environment boot.
 - faster tests + console
 - able to boot environment without/with empty/with old database

Recommended: turn your observers into modules

```Ruby
module CachingObserver
  def self.included(base)
    this = self
    base.after_save { |record| this.do_something(record); true }
  end

  def self.do_something(record)
     ... do something ...
  end
end
```


Install
=======

    gem install lazy_observers

Usage
=====

    class FooObserver < ActiveRecord::Observer
      lazy_observe "User", "Foo::Bar"

      ...
    end

### Extend models from gems after they are loaded

    LazyObservers.on_load("Arturo::Feature") do |klass|
      klass.class_eval do
        ... funky hacks ...
      end
    end

### Catch models that are loaded in application startup.

    LazyObservers.debug_active_record_loading

`script/console` or `rails c`

### Verify you did not misspell
Loads all classes registered via observers, to make sure you did not misspell</br>
(negates the effect of lazyness, so only use for debugging)


    LazyObservers.check_classes

TIPS
====
 - .on_load is called before all methods are defined on the baseclass, so they might not be defined
 - do not use observe and lazy_observe in the same observer (and if you have to, use observe after lay_observe)
 - do not use Model classes with class-methods of the observer e.g. class FooObserver; Foo.something{}; def after_update; end; end
