/** \name Geometry I/O

    The geometry I/O support currently handles geometry composed of
    - IMP::display::SegmentGeometry
    - IMP::display::CylinderGeometry
    - IMP::display::SphereGeometry

    Other types can be supported when requested. Be aware, many
    more complex geometry types are automatically decomposed into
    the above types and so, more or less, supported.
