* Description:
"Class" function in Javascript: it is intended to be a really light copy of the MooTools’s Class function with basic features; i am working with jQuery at the moment and i miss this amazing function!

* Goals:
- Encourage objective Javascript instead of sequential programming (!)
- MooTools syntax compatibility (means be allowed to move the code on MooTools or project like moo4q in the future)
- Get an unique class-pattern (avoiding mixed code like using prototype and closures patterns togheter)
- Moving the focus from the function to the prototype, for the functions constructor modelling
- Get lighter classes by provide tools for code reusing 
- Class powered by really light code, easy to be mantained by me (or you!)
- Basic functionalities: extend, implement, parent method, the function “initialize” as constructor (and as minor: setOptions)

* Todo:
- Instantiate the Class should need the new operator, like the MooTools one.
- The setOptions method is missed at the moment, i think it is really useful, inside the constructor, in a lots of situations.
- If there is a this.parent() call from a sub method to a super that doesn't exist you should trigger an error (for MooTools compatibility).
- As minor, classes from MooTools get these properties on their prototype:
  parent, $constructor
  The same properties are missed, or there are but with a different behaviour, using my Class function.
  The same is for the instances of a class defined by MooTools, they get these property (missed or not the same behaviour using mine):
  $caller, caller, $constructor, parent

* How to build it:
The Makefile is in src-min/ .
The Makefile builds all the modules in src-dev/ in one file: src-min/class-min.js ; that is the file to include in your pages.
To build your own classes-min.js, you should know that the Makefile looks for the Google's Closure Compiler:
https://developers.google.com/closure/compiler/
The path of the compiler is specified by the var in the Makefile.


I wrote it in my current company, WCN (wcn.co.uk), and i was allowed to release it as open source. Thanks (particularly to Jack Hobson) you!
