Advanced Taming AI Help

Hello all, I am trying to learn the best way to actually code custom Creature Taming. I am aware you can use the AI Base of a Wolf or an Ocelot, but I am trying to steer away from that in light of something more specific/in-depth.  Has anyone learned how to create the "taming" block of code? 

Essentially, I want to give my custom mob an item to tame it, and use the general "following" rules. I have seen a lot of topics about using an AI base, and I have spent the last few hours studying the wolf code and "EntityTameable," but I think I am going to need some help. 

I appreciate any replies!
