Polimorphism               The same message applied to different Objects
--------------------------------------------------------------------------------

  The same message sent to Objects of different Classes, invokes different
  methods.

  Supouse we have a ball and a glass. Then I take a hammer and I knock
  on them:

  My message   -->  HammerKnock

  Object Ball  --> start jumping from one place into another.

  Object Glass --> Gets destroyed into a lot of small pieces.


  Now I have a TReport() Object and a TLabel() Object:

  I send them the message :Print()

            oReport:Print()
            oLabel:Print()

  I get different results on my printer!
