Reusing an AngularJS Directive core code. The idea is to:  

** 1. conceal the actual directive behaviour in a separate JS "class", 
** 2. store that in an Angular service, 
** 3. inject that service into an Angular directive, 
** 4. just have the directive factory function return the constructed instance of the "class".

That is to separate the directive core code from the actual directive factory. 
Then one actually wants to inherit a directive core "class" from another. It's not really a matter of JS inheritance, but more on how to inject one into the other by means of Angular modules, without actually instantiating none of them until needed,
