Detailed Description

A tank described by a measured or CAD-derived *V(h)* table.

The escape hatch, and for a real flight tank usually the right answer: a
weld land, a sump, a baffle ring and an anti-vortex plate are all volume
that no analytic shape has, and CAD already knows about every one of them.

Args:
    levels: Heights above the lowest point [m], strictly increasing, the
        first at or below zero and the last the full height.
    volumes: Cumulative volume below each level [m^3], non-decreasing.
    areas: Optional horizontal cross-section at each level [m^2]. Derived
        by differencing the volume table when omitted, which is exactly
        ``dV/dh`` and needs no extra data.
    wall_areas: Optional cumulative wetted wall area [m^2].
