Note: @colemanw This is my first directive in Angular, Let me know if something is going wrong in this.

Ideally, all the ad-hoc affix jquery would be turned into directives like this one. By adding a few parameters you could probably do a single directive that worked for all of them.

I thought of that but, we need extensive calculations on other affix and that affix are dependent on their previous one and it's height as well. so, that makes me stop it from adding all things in one.
