    Eq Area
    The Eq Area record specifies, very simply, the name of a
    branch in the equipment tree, and its relative precedence over its
    sibling branches.  If Parent ID is blank, it will appear at
    the top level; the convention is to have one top-level branch for
    every lab.  If Parent ID refers to an area that does not
    exist, it will not appear at all.  Rank specifies its
    rank: lower values appear sooner (more towards the top) in the
    equipment tree.  Two entries with the same rank are sorted
    alphabetically.
