/*
 * A ListCtrl with headers appropriate for viewing archive contents.
 *
 * NOTE: this class performs auto-cleanup, and must be allocated on the heap.
 *
 * We currently use the underlying GenericArchive as our storage for the stuff
 * we display.  This works great until we change or delete entries from
 * GenericArchive.  At that point we run the risk of displaying bad pointers.
 *
 * The GenericArchive has local copies of everything interesting, so the only
 * time things go badly for us is when somebody inside GenericArchive calls
 * Reload.  That frees and reallocates the storage we're pointing to.  So,
 * GenericArchive maintains a "I have reloaded" flag that we test before we
 * draw.
