    @nvazquez and @pedro-martins, 
    I am ok with the code now, expect the constructor bit.
    The question you should ask about the constructor is, is it used NOW? If not, why create
it. In the future when the need appear, we can create it; this way we can avoid unused code
that may be left aside and never used.
    
    Additionally, I am with @pedro-martins, if you like, tests cases would be pretty welcome
here.
