Style 03-03: Add one more "why"

[stasberkov]

Is is hard to persuade developers with C# background to name interfaces without I prefix. The following "Why" could be helpful: Naming interfaced without I forces developers to give proper name to abstraction and concrete implementation, emphasizing their differences e.g. SportsCar->Car, SuvCar->Car vs just Car->ICar.
Please add it to ng2 style guide.

Mfw I've been writing C# for ages and then a guy tells me "List" in java is an interface.

The Angular 2 interfaces don't follow this style, e.g. CanActivate, OnInit

I dissagree on not naming interfaces with an I, because when you just see the code files, you can't tell if it's an interface or not...... The I is very helpful here! It has nothing to do with not being able to name the actual abstraction, @stasberkov, it's all about code readability.....
