/**
* ParentSHistory is the ultimate source of truth for a browsing session's
* history. It lives in the parent process and stores the complete view of
* session history.
*
* NOTE: Currently session history is in transition, meaning that we're still
* using the legacy nsSHistory class internally. This means that currently the
* session history state lives in the content process, rather than in this
* class.
