Description: Plots Tanner pubertal stage measurements (genital, pubic hair,
    testicular volume, breast, menarche) against Dutch 1997 growth-study
    references as stage line diagrams, and converts observed stages to
    age-conditional standard deviation scores (SDS). Testicular volume can
    be entered as a raw orchidometer reading in ml. Implements the method
    of van Buuren and Ooms (2009) <doi:10.1002/sim.3567>.
