/**
* ModifierChain
* -------------
*
* ModifierChain is a class to add and remove a chain of modifiers
* at a single point in the render tree. Because it add exists
* in a single element, it has slight performance benefits over
* chaining individual modifiers.
*
* In the example, you can see that on the click event we are able
* to remove a modifier after it has been added to the render tree.
