Update 04/02/2014 (Version 0.12.0)

* Encapsuled library into a self invoking function, that expose the
references ‘Nest’ and the alias ‘$$’ (the alias can be changed by
changing the parameter)
* Nest is now a self instancing function
* Utility functions are now callable directly without creating a new
instance, by i.e. ‘Nest.notify(…)’ or ‘$$.notify(…)’
* Bugfixes
