CRITICAL
- Reloading resourses in ClassXXX.res folder doesn't works.
- Change 'raise_without_self' to caller.delete(SomePackage)

MEDIUM
	 
LOW
- Add macros functionality to Ruby. (for example replace all '!=' with 'not_equal')
- Create project 'Flawless Ruby' (macros != to not_equal, and so on)
- Automatically evaluate extension for resources, use Class["res"] instead of Class["res.yaml"]

DONE
- Add resource providers chaining.
- Resource providers should be abstract (also for ObjectModel storage).
- Cashe implementation    
- Resource reloading doesn't works (fix and add spec).
- Add raise_withoud_self 'bla-bla', [excludeAclass, excludeBclass]
