Mixin which defines a component's content as its children, expanding any nodes distributed to the component's slots.
This mixin is intended for use with the DistributedChildren mixin. See that mixin for a discussion of how that works. This DistributedChildrenAsContent mixin provides an easy way of defining the "content" of a component as the component's distributed children. That in turn lets mixins like ContentAsItems manipulate the children as list items.
The content of this component, defined to be the flattened array of children distributed to the component.
