- * on that group, and what is the active element on the group (the frame that
- * holds the loaded content).
- * The reference to the activeFrame is a weak reference, which allows the
- * frame to go away at any time, and when that happens the module considers that
- * there are no active elements in that group. The group can be reactivated

- * class of this module which does not automatically keep track of its state. This
- * object should not be used externally, and all control should be handled by the
