Traits for java

[Jose Antonio Illescas Del Olmo]

I don't know if this list is the best place to submit this request.

One interesting feature can be Traits (interfaces with implemented methods)


      Split multiples functionalities on each Traits and remove 
macro-classes with macro-functionalities


Please see: http://code.google.com/p/groovypptest/wiki/Traits

    PD: this change is minimun from a java coder view (some methods on 
interfaces can have a default implementation)
