Chain has 2 main methods and you have to use both in order for it to do
anything:
chain - pushes a function onto the stack
callChain - calls the next function on the stack
so if you want to do:
this.fn1().chain(this.fn2.bind(this));
then fn1 has to have this in it:
fn1: function(){
...some logic that you want to execute
this.callChain();
return this;
}
