IIterator Interface

Objects that Implement this Interface share a common interface of how to iterate through a container.

So if a object Implements this interface then you can always talk to it with the IIterator interface methods.

Note:
Interfaces don't actually do anything. A Interface is just a promise of what methods a implementor of a interface will have.
