/*
    An Object is considered to be a **functor** when it implements fmap (fmap referring to functor map not flatmap)
   -[Rules] This fmap should 
       * preserve Identity (x to y) and (y to x ) should be the same value every time 
       * and be composable 

   map isn't fmap  but fmap can do what map does 
   map only operates on pure function, where fmap is lifted that pure function to operate on functor type

Instead of the verbose setOnClickListener:

RxView.clicks(submitButton).subscribe(o -> log("submit button clicked!"));
