/**
 * Defines an interface for genes that are simply containers for attributes
 * for its parent element. These attributes may or may not be actually
 * generated, depending on certain conditions and on the kind of Container
 * object.
 *
 * Containers may also have elements. Since a container is also a gene, such
 * elements are generated by calling the generate() method from that
 * interface.
