Quizzer::Element::Container - Container input element
This is a Container input element. A Container is an element that can hold other elements that are displayed when it is.
This function sets/gets a Container's question property, as usual. It also handles creating and setting up all the Elements inside the container.
Containers are visible if any of the items contained in them are visible. Or are they? This is still being decided -- TODO.
When a container is displayed, it displays all elements inside it.
