Version:   Beta 2.0

  This version was built from the previous one. It has the following modifications:
  
 1) The name of run and call instruction was changed. Now the run instruction (imple
    mented with the Run Junior instruction) is called call and the call instruction
    is called inline.

 2) Many reactive instructions were extended, i.e. its grammar was changed in order 
    to increase the expresivity of the language. The instructions modified are those 
    that use events and the repeat, if, call and inline instructions.

 3) It was fixed the bug when there are two or more methods with the same name 
    but different signature.  

 4) The agenst struct was modified in order to not depend of REJO language.
    Now the migration is started by the generation of a valued event.
